1.3 Overview of Tools
The following provides an overview of the software tools included in the package.
Simulator (Sim63.exe, Sim88.exe)
This software simulates device operations and debugging on a PC. Various functions are executed using commands entered from the keyboard or from files. Frequently-used break and single-step commands are registered to the toolbar to minimize repetitive keyboard tasks. Program code, register contents, and command execution results can be displayed in a multi-window screen to facilitate debugging. You can also simulate push-buttons or key matrix that use I / O ports and LCD displays. A different simulator is provided for each of the S1C63 Family (Sim63) and S1C88 Family (Sim88) microcomputers.
Auto evaluation system (AutoEva.exe)
Common to S1C63 / S1C88 Family
The auto evaluation system runs with a simulator (Sim63 / Sim88) on a personal computer to check the operation of a target program in an automated sequence (issue of key events and verification of LCD screen and memory contents). The inspection procedure is saved to a file, allowing users to assess program operation at any time by tracing the procedure. By automatically evaluating program operations using the same inspection procedure used before the revision, this package helps uncover bugs and software errors arising from program modifications.
LCD panel customize utility (LcdUtil.exe)
Common to S1C63 / S1C88 Family
This utility creates a panel layout and COM / SEG port assignment data required by the simulator (Sim63 / Sim88) to simulate a monochrome LCD panel display. Icons and other display objects are loaded from bitmap files (.bmp) and may be created with general-purpose paint software, enabling simulation of the actual product screen.
Bitmap utility (BmpUtil.exe)
Common to S1C63 / S1C88 Family
This utility creates bitmap image data (e.g., character data) for the dot matrix LCD display. The output data is created in the assembly source format with specified labels assigned to it to allow you to assemble data without modifications and link it to the program.
Port setting utility (PrtUtil.exe)
Common to S1C63 / S1C88 Family
This utility creates port setting data for the simulator (Sim63 / Sim88) to simulate target key events using the PC keyboard.
Logic analyzer (LogAna.exe)
Common to S1C63 / S1C88 Family
This utility loads a log file created in the I / O Terminal window of the simulator (Sim63 / Sim88) and displays the I / O port status recorded in the file as a waveform.
ROM data setting utility (Rom88.exe)
Only for S1C88 Family use
This utility loads a ROM image data file in binary format to the simulator (Sim88). It can also save the memory data patched in the Sim88 Dump window to a ROM image data file. These tools run under Windows® 95 / 98 and Windows NT® 4.0.

3.3 Overview of Simulation Functions and Operations
This section explains how the target application is simulated on a PC with the simulator sim63.
Supported MPUs
The current simulator version supports all applications using one of the following MPUs: S1C63158, S1C63358, S1C6P366, S1C63454, S1C63455, S1C63458, S1C63466, S1C63467, S1C6P466, S1C63557, S1C63558, S1C63567, S1C63666
Target applications
This simulator is best suited to simulating applications that require key input and LCD display functions, such as watches, pocket calculators, electronic pocketbooks, and portable games. OSC1 clock operation can be executed in real time. For OSC3 operation, real-time execution is possible in the range of 500 kHz to 1 MHz. (With PCs running on a 400-MHz Pentium or equivalent or faster and 64 MB RAM, real-time execution for approximately 500 kHz is possible.) However, for reasons involving instruction-level simulation accuracy, it is not possible to simulate high-accuracy timing tasks such as those for control systems. Support for external devices is limited to monochrome LCD panels, backlight, keys, and a key matrix.
Note: Simulation on a PC is subject to some other limitations. The formal release version will support a greater number of external devices. See Section 3.15, "Restrictions", and the readme.txt file.
Entering schematic information into the simulator
To set the information required to simulate the operation of external devices, load data from files. Mapping of external devices and the internally-generated clock frequency Create a component mapping file (file.cmp) by writing addresses to which external devices (e.g. backlight control bit) are mapped, then load the file into the simulator. This allows simulated control of these external devices. Use the component mapping file to set simulation conditions such as OSC1 / OSC3 oscillation clock frequencies. For more information on creating this file, see Section 3.12, "Component Mapping File (.cmp)". Entering key and key matrix specifications Create a port setting file (.prt) containing a description of the relationship between key input ports and the I / O ports comprising the key matrix and target and PC keyboards, then load the file into the simulator. This allows simulated key input with the PC keyboard. For more information on creating this file, see Chapter 8, "Port Setting Utility". Entering LCD design Create an LCD panel definition file (file.lcd) containing a record of LCD panel layout and SEG / COM port assignments, then load the file into the simulator. This allows simulated display on LCD panels. For more information on creating the LCD panel definition file, see Chapter 6, "LCD Panel Customize Utility". These files normally are loaded when the simulator starts.

Fig. 3.4.1 Input / output files
This file contains memory information on each microcomputer model and is indispensable for starting the simulator. This file is included in the S1C63 Family Assembler Package.
This is an object file generated by the linker. This file is read into the simulator by the lf command. By reading a file in the IEEE-695 format that contains debug information, source display and symbolic debugging can be performed.
This is the source file of the above object file. It is read when the simulator performs source display.
This is a load image file (HEX file in Motorola S2 format) of the code ROM, and is read into the simulator by the lo command. The file ".hsa" corresponds to the 5 high-order bits of the program code and the file ".lsa" corresponds to the 8 low-order bits of the program code. These files are generated for the purpose of creating mask data from an object file in the IEEE-695 format by the Hex convertor. Unlike files in the IEEE-695 format, these files cannot be used for source display or symbolic debugging, but can be used to check the operation of final program data.
This is a load image file (HEX file in Motorola S2 format) of the data ROM, and is read into the simulator by the lo command. This file is generated for the purpose of creating mask data from an object file in the IEEE-695 format by the Hex convertor. When an absolute object file in the IEEE-695 format is loaded, it is not necessary to load this file.
This is the mask option setup file in Motorola S2 format that is generated by the function option generator. This file is read by the lo command.
This is the mask option setup file in Motorola S2 format that is generated by the segment option generator. This file is read by the lo command. Some models have no segment option, but a HEX file is provided for setting up the simulator.
This file is used to specify a parameter file, LCD panel definition file, component mapping file and port setting file at the simulator start up. Enter file names using an editor to create this file. The simulator can be started up if this file does not exist by selecting the files from a dialog box.

(2) Capturing the panel image Camera button Clicking this button captures the LCD panel image at that point and then transfers it to the clipboard as a bitmap image. The captured image can be pasted to paint software to print and / or saved to a file. Since this button is invalid during program execution, program execution must be broken at the desired image before it can be captured. Video button Clicking this button enables the panel image recording function (can be saved as an AVI file). When starting the program execution in this status, two dialog boxes to specify a file name and a video compression format appear sequentially. Enter a file name and choose an available video compression format. The recording continues until the program execution is broken. The generated file can be played back with the Windows standard medium player. This button cannot be cancelled after it has been clicked once. To cancel the recording, click on the Cancel button in the file name input dialog box. The program will be executed, but the recording is cancelled.
Note: The recording operation reduces the program execution speed.
(3) Key entry simulation If the program being executed is waiting a key entry, key entry operation can be simulated using the PC keyboard after activating the LCD window. The correspondence between PC keys and ports should be defined in the port setting file. This definition list can be displayed using the Key List button. Key List button The displayed contents are port name, target key name and PC key name, respectively from the left. The correspondence between PC keys and target keys can be verified here. The symbol on the left indicates the port status H indicates that the port is high level and L indicates low level. The input level is different by the port specification of the model. The key entry status can also be set in break status. The key entry status is maintained during the next program execution until the user operates the key. This allows setting of the key entry status during single-step operation. The input port is fixed at active level if the pressed key is directly connected to the input port. In the case of a key matrix, the input port goes active level only when the corresponding output port goes active level. (4) SVD simulation This slider changes the detection level of the SVD to 17 steps.
(5) Simulating serial / general-purpose port input / output and A / D conversion Use the I / O button to display the I / O Terminal window and to load an IOT file. This allows simulation of serial interface input / output, general-purpose port input / output, and A / D conversion. For more information, refer to the next section. I / O button

3 S1C63 FAMILY SIMULATOR
3.9.3 Executing from a Command File
Another method for executing commands is to use a command file that contains descriptions of a series of debug commands. By reading a command file into the simulator the commands written in it can be executed.
Creating a command file
Create a command file as a text file using an editor. Although there are no specific restrictions on the extension of a file name, Seiko Epson recommends using ".cmd". Command files can also be created using the rec command. The rec command creates a command file and saves the executed commands to the file.
Example of a command file
Reading in and executing a command file
The simulator has the com and cmw commands available that can be used to execute a command file. The com command reads in a specified file and executes the commands in that file sequentially in the order they are written. The cmw command performs the same function as the com command except that each command is executed at intervals specified by the md command (1 to 256 seconds). Example: com start.cmd cmw test.cmd The commands written in the command file are displayed in the Command window.
Restrictions
Another command file can be read from within a command file. However, nesting of these command files is limited to a maximum of five levels. An error is assumed and the subsequent execution is halted when the com or cmw command at the sixth level is encountered.

3.9.4 Log File
The executed commands and the execution results can be saved to a file in text format that is called a "log file". This file allows verification of the debug procedures and contents. The contents displayed in the Command window are saved to this file.
Command example
Display of Command window in log mode
The contents displayed in the Command window during log mode differ from those appearing in normal mode. (1) When executing a command when each window is open (When the window that displays the command execution result is opened) Normal mode: The contents of the relevant display window are updated. The execution results are not displayed in the Command window. Log mode: The same contents as those displayed in the relevant window are also displayed in the Command window. However, changes made to the relevant window by scrolling or opening it are not reflected in the Command window. (2) When executing a command while each window is closed When the relevant display window is closed, the execution results are always displayed in the Command window regardless of whether operation is in log mode or normal mode.

3.10 Debug Functions
This section outlines the debug features of the simulator, classified by function.
3.10.1 Loading Files
Table 3.10.1.1 lists the files read by the simulator and the load commands. Table 3.10.1.1 Files and load commands
Files 1 to 4 are required for starting the simulator. Either a parameter file (1) or a simulator project file (5) must be selected in the dialog box shown below at the first time the simulator starts up. Enter the parameter file name or simulator project file name to the text box, or choose it using the Browse.. button. If the Show this window at startup check box is deselected, this dialog box will not appear from the next startup of the simulator and the same file will be selected. Loading a parameter file resets the simulator. The memory mapping information set by the parameter file can be displayed using the ma command. When a parameter file is selected, the dialog box shown below appears to select files from 2 to 4. When a simulator project file is selected, this dialog box does not appear because the file names (2 to 4) are specified in the file. Enter a component mapping file name, LCD panel definition file name and a port setting file name to the respective text boxes, or chose using the Browse.. button. These files are selected once, the file names will appear in the text boxes at the next startup of the simulator allowing choice of the files by clicking the OK button only. The lf command loads an absolute object file (.abs) in the IEEE-695 format. To perform source display and symbolic debugging, load an object file that contains the debugging information in this format. Furthermore, the source files must be located in the original directory. The lo command loads a program / data files (.hsa, .lsa, .csa) or an option HEX file (.fsa, .ssa) in the Motorola S2 format. When files in this format are loaded, the Source window can display the program code only in unassemble mode. For the command file, refer to Section 3.9.3.

3.10.4 Executing Program
The simulator can execute the target program successively or execute instructions one step at a time (single-stepping).
Successive execution
(1) Types of successive execution There are two types of successive execution available: · Successive execution from the current PC · Successive execution from the program start address (0x0110) after resetting the CPU Table 3.10.4.1 Commands / menu items / tool bar buttons for successive execution
(2) Stopping successive execution Using the successive execution command (g), can specify up to two temporary break addresses that are only effective during program execution. The temporary break address can also be specified from the Source window (one location only). If the cursor is placed on an address line in the Source window and the Go to Cursor button clicked, the program starts executing from the current PC address and breaks before executing the instruction at the address the cursor is placed. Except being stopped by this temporary break, the program continues execution until it is stopped by one of the following causes: · Break conditions set by a break set up command are met. · The Key Break button is clicked. · A map break, etc. occurs. Key Break button When the program does not stop, use this button to forcibly stop it.
(3) Simulation for LCD panel display and external input / output The LCD window shows the LCD panel images according to the program sequence during the program execution. It also allows simulation of key inputs using the keyboard of the computer. These functions are configured with the component mapping file, LCD panel definition file and port setting file loaded at the startup of the simulator. See Section 3.6.3, "LCD Window", for more information. Furthermore, serial / general port inputs / outputs and A / D conversion can be simulated by reading an IOT file from the I / O Terminal window. See Section 3.6.4, "I / O Terminal Window", for details.

3 S1C63 FAMILY SIMULATOR
Single-stepping
(1) Types of single-stepping There are two types of single-stepping available: · Stepping through all instructions (STEP) All instructions are executed one step at a time according to the PC, regardless of the type of instruction. · Stepping through instructions except subroutines (NEXT) The calr, calz and int instructions are executed under the assumption that one step constitutes the range of statements until control is returned to the next step by a return instruction. Other instructions are executed in the same way as in ordinary single-stepping. In either case, the program starts executing from the current PC. Table 3.10.4.2 Commands / menu items / tool bar buttons for single-stepping
When executing single-stepping by command input, the number of steps to be executed can be specified, up to 65, 535 steps. When using menu commands or tool bar buttons, the program is executed one step at a time. In the following cases, single-stepping is terminated before a specified number of steps is executed: · When the Key Break button is clicked. · When a map break or similar break occurs. Single-stepping is not suspended by breaks set by the user such as a PC break or data break. Key Break button When the program does not stop, use this button to forcibly stop it. (2) Display during single-stepping In the initial simulator settings, the display is updated as follows: The display contents of the Register window are updated every step. If the Register window is closed, its contents are displayed in the Command window. This default display mode can be switched over by the md command so that the display contents are updated at only the last step in a specified number of steps. The display of the Source and Data windows are updated after the specified number of step executions are completed. (3) HALT and SLEEP states and interrupts The CPU is placed in a standby mode when the halt or slp instruction is executed. An interrupt is required to cancel this mode. The simulator has a mode to enable or disable an external interrupt for use in single-step operation. Table 3.10.4.3 External interrupt modes
External interrupt halt and slp instructions Enable mode Interrupt is processed. Executed as the halt instruction. Processing is continued by an external interrupt or clicking on the Key Break button. Disable mode Interrupt is not processed. The halt and slp instructions are replaced with a nop instruction as the instruction is executed.
In the initial settings, the simulator is set to the interrupt disable mode. The interrupt enable mode can also be set by using the md command. (4) Key entry simulation during single-stepping Key entry status can be set on the Key List window displayed by clicking on the Key List button on the LCD window and is maintained during single-stepping.

Resetting the CPU
Table 3.10.4.4 Commands / menu items / tool bar buttons for resetting CPU
The CPU is reset when the gr command is executed, or by executing the rst command. When the CPU is reset, the internal circuits are initialized as follows: (1) Internal registers of the CPU PC A, B X, Y, QUEUE F SP1, SP2, EXT .. 0x0110 .. 0xa .. 0xaaaa .. 0b0000 .. 0xaa
(2) The execution cycle counter is reset to 0. (3) The Source and Register windows are redisplayed. Because the PC is set to 0x0110, the Source window is redisplayed beginning with that address. The Register window is redisplayed with the internal circuits initialized as described above. The data memory contents are not modified.

3.10.5 Break Functions
The target program is made to stop executing by one of the following causes: · Break command conditions are satisfied. · The Key Break button is activated. · A map break or similar break occurs.
Break by command
The simulator has five types of break functions that allow the break conditions to be set by a command. When the set conditions in one of these break functions are met, the program under execution is made to break. (1) Break by PC This function causes the program to break when the
