C164 Memory Programming
Memory Overview
C164CI devices provide KBytes one-time-programmable ,,OTP" memory on-chip both instruction code constant data. C164CI module KBit memory organized double words each. interface presents fast read access (60ns fCPU MHz) machine cycle. Read accesses code data possible addressing mode, thus realizing highest performance with fetch execution double word instructions single instruction cycle. programming testing purposes special interface realised which directly connects module external internal (CPU) host. Programming performed steps 16-bit words, needing typically word. Special algorithms over-/ under-programming, with verify operations, necessary. programming voltage supplied pin. Unprogrammed memory cells contain '1's. memory programmed both appropiate programming board (supplier: Ertec, SMS, Data I/O) target system which provides flexibility. lower KBytes on-chip memory C164CI mapped either segment (00'0000H 00'7FFFH) segment (01'0000H 01'7FFFH) during initialization phase allow external memory used additional system flexibility. upper KBytes onchip memory assigned locations 01'8000H 02'0000H (figure

Memory Configuration
Upon reset default memory configuration C164CI determined state pin. When internal memory disabled startup code fetched from external memory. order access on-chip memory after booting from external memory internal memory must enabled software setting ROMEN register SYSCON. lower KBytes memory mapped segment segment controlled ROMS1 register SYSCON. Mapping segment preserves external memory containing startup code, while mapping segment replaces lower KBytes external memory with onchip memory. this case valid vector table must provided. on-chip memory covers more than segment segmentation should enabled clearing SGTDIS register SYSCON) order whole internal into address space. Whenever internal memory configuration C164CI changed (mapping, enabling, disabling) following procedure must used ensure correct operation: Configure internal memory required Execute inter-segment branch (JMPS, CALLS, RETS) Reload four registers
Note: Register SYSCON only modified before execution EINIT instruction. Note: detailed informations concerning handling internal non-volatile memory please refer users manual, chapter ,,System Programming" (Handling Internal ROM/ Pits, Traps Mines).

Host Mode (CHM) Selection
in-system programming necessary activate programming interface which realized XBUS peripheral. C164CI enters with port P0L.2 during reset. useful combine this mode with bootstrap loader mode (see next chapter). Memtool OTP/ Flash Memory Programming Tool
In-system programming on-chip OTP- Flash memory supported Windows-based programming tool ,,Memtool" which freely available. Siemens provides driver updates Internet; please current status. Memtool application example well programming tool on-chip OTP- Flash memory, supporting C161CI-32F, C167CR-16F, C167CS-32F C163-16F Flash devices C164CI-8E devices. Thanks modular structure Memtool easily expandable future C16x devices. interested user driver sources also available (figure Along with drivers come readme.txt files which contain informations about hardware requirements latest informations about Memtool each driver.

C164CI already provides asynchronous serial interface that only connected COM1 COM2 your Supposing using Phytec C164CI starter kit, directly connect serial connector with COM1/ COM2 interface your Note: getting started steps needed: Activate bootstrap loader mode enter host mode (these modes activated with port pins P0L.2 P0L.4 "LOW" during reset; simple 8.2k pull down resistors applicable) Connect target with C164CI device host with serial cable. Special Memtool Options
default Memtool expects serial communication RS232. Some drivers also support singlewire transmission (K-Line). drivers which support K-Line protocol marked with "KL" (see "Target"/ "Change"/ "Select Controller Type"). Select desired mode (RS232 K-Line) "Interface" "Setup Interface". some cases also useful LOG-file transmitted data. LOG-file generation switch "DIAGLOG" Memtool configuration file (memtool.ini/ siemtool.ini) "1". LOG-file will closed leaving Memtool. switch currently implemented. Pits, Traps Mines
prevent controller from beeing damaged, generally main power must connected before disconnected after Vpp. Also microcontroller programming mode (CHM EHM) when applying Vpp. case in-system programming Memtool controller must programming mode. data transmission speed K-line (single-wire) increased, when FIFO used communication port (COM1, COM2) deactivated. C164CI enters bootstrap mode P0L.4 sampled hardware reset. this case activated, independent selected mode; evaluation (external access) bootstrap loader mode. host mode (CHM) default setting BUSACT0 register BUSCON0 "1", which means: external enabled. single-chip applications this might could lead problems with external peripherals, because accesses programming interface (respectively registers OPAD, OPDAT, OPCTRL) seen externally. this case necessary reset BUSACT0 before performing first programming interface access. default setting Semiconductor Group AP1639 02.99

BUSACT0 independent SYSCON settings. C164 drivers BUSCON0 (and therefore BUSACT0) zero module "load_2". Note: Since device step setting BUSACT0 register BUSCON0 depends host mode (CHM) state during reset: P0L.2 "low" (CHM) "low": BUSACT0 (external enabled) P0L.2 "low" (CHM) "high": BUSACT0 (external disabled) Programming Drivers Overview
Several programming drivers available. This founded different demands different applications. following overview just snapshot status quo. future versions will available which will partly replace current ones. Please attention readme.txt files which come along with drivers. fact that design step possible perform read accesses host mode (CHM), success programming operation only verified normal mode reading content ROMbus (see chapter 6.1). Since design step read accesses also performed CHM. Read accesses (like write accesses) controlled operation control register OPCTRL. Normal data read accesses without right OPCTRL setting would deliver dummy zero values "0000 long controller CHM. Furthermore necessary that during verify read accesses level limited Volt lower. C164 drivers properly tested with 9600 Baud transmission rate. readme.txt files sub-directories Memtool (memtool/ siemdrv/ C16x.) contain important informations about each driver version: C164CI Standard RS232 external disabled (BUSCON0=0000h) EINIT system clock output enabled switching control port C164CI cv_A (customized version RS232 external disabled (BUSCON0=0000h) EINIT system clock output enabled switching control port
