HDS2 mainframe (with MB097 main Board) been designed replace HDS1 version. main modifications are: Communication transfer rate: much faster thanks parallel port. Dimension weight: boards, basic part system, have been redesigned board. cost overall system been well reduced. second version HDS2, (metal with MB174 main Board) modified conformity, these features have been introduced: Read/ Write registers during execution program without wait state. Selective record logical analyser Range Start/Stop mode. Output OUT1 OUT2 synchronisation external equipment, programmable same Selective trace, Range Start/ Stop mode. Figure Hardware Development System Emulator Stack overflow: break automatically generated default) case stack overflow. Break execution: this version, program stops before execution fetch. These main frame consist basic part, common devices, ST62 ST63 family dedicated board depending specific device emulate. This emulator full compatible with existing dedicated boards, excepting ST631XX-DBE which have been designed boards. Only dedicated board changed emulate device within ST62/ST63 families. parallel port allows very faster communication transfer rate. symbolic debugger, software part real time emulation tool, common ST62 ST63 devices. debugger uses windowed menu driven interface, enables user configuration emulator.

TROUBLESHOOTING
POWER beginning emulation session, screen must appear debugger message software connection establishment. "TIMEOUT" message encountered, there connection problem, which come from these reasons: with ST6HDS2 development Tool power parallel line well connected with main frame: verify that delivered cable actually connected directly Main Frame. necessary there another cable which either "wire wire" connection adaptor. serial line connected right port computer. DURING EMULATION: PROBLEM WITH PROGRAM COUNTER case "Check Hardware Jumpering" wrongly executing code step mode: Most time, this problem occurs with HDS1 emulator with HDS2 plastic version, coming from that development tool RESET state, caused application where probe connected powered then schmitt trigger Reset active causes RESET Reset emulated device level probe connected, powered either application voltage input. properly emulating RESET please refer following chapter. RESET EMULTATION REAL TIME With ST6HDS2 metal box, possible begin emulation session even application off, required particularly MONITOR applications. With HDS1 emulator, with HDS2 plastic Version, application requires that software must executed just after power mandatory proceed follow: connect, remove probe from application. power emulator. begin emulation session: load program. then start execution program Real Time. plug probe application (which off), this time emulator reset state, because Reset pins level. Power application, then execution software will start. DISCREPANCIES BETWEEN EMULATOR EPROM DEVICE When some differences behavior appearing between emulator device, most cases, comes from using read/modify/write instructions registers which some bits writable, some bits readable. these registers, trouble caused, because when reading, random value read CPU, after calculating mask, this random value written register, changing unintentionally! same problem occur with registers, where some bits have different function during writing during reading. Example Ports: When reading port input mode, read value level pin. When reading port output, read value value corresponding Data Register. case problems check each used register correctly accessed. principle registers (depending family), with which care must taken, listed below: EEPROM control registers control registers SPIs Data registers Ports Analog Digital Converter Control Register Sync Processor control registers bits (PWM+BRM) converter NMI/PWR/VSYNC Interrupt Register Interrupt Option Register Program Pagination Registers

Data RAM/EEPROM Banking Register Data window Register offer more flexibility user, these registers readable outside real time.(undefined bits read value). AVOID MOST FREQUENT PROBLEMS WHEN PROGRAMMING MICROS! 5.5.1 Execution Interrupt interrupt executed, most cases, comes from: core normal mode: after RESET core mode, enter normal mode which execute interrupt, core must execute RETI instruction. global enable interrupt been SET, been unintentionally cleared, then register must checked. default value enable Interrupts 010H.
enable interrupt desired peripheral been SET, been unintentionally cleared. Interrupt Option Register write only, been wrongly written read/modify/write instruction, only permitted. 5.5.2 Execution WAIT STOP instructions WAIT mode, WAIT STOP mode WAIT STOP front panel emulator). STOP WAIT instructions exited, comes from: core normal mode: after RESET core mode, enter normal mode which execute interrupt exit from these states, core must execute RETI instruction. Explanation: only STOP WAIT state have INTERRUPT RESET, reason why, execute these instructions interrupt must have been validated.
