MC96F6432SABOV Semiconductor Co., Ltd.1.3 Development tools1.3.1 CompilerABOV Semiconductor does not provide compiler. It is recommended that you consult a compier provider.The MC96F6432S core is Mentor 8051, and the ROM size is smaller than 64Kbytes.Therefore, developer can use thestandard 8051 compiler from other providers.1.3.2 OCD(On-chip debugger) emulator and debuggerThe OCD (On Chip Debug) emulator supports ABOV Semiconductor’s 8051 series MCU emulation.The OCD interfaceuses two-wire connection between PC and MCU which is attached to user’s system. The OCD can read or change thevalue of MCU internal memory and I/O peripherals. And the OCD also controls MCU internal debugging logic, it meansOCD controls emulation, step run, monitoring, etc.The OCD debugger program works on Microsoft-Windows NT, 2000, XP, Vista (32-bit) operating system.If you want tosee more details, please refer to OCD debugger manual. You can download debugger S/W and manual from our website(http://www.abov.co.kr).Connection:DSCL (MC96F6432 P01 port)DSDA (MC96F6432 P00 port)NOTE)1. MC96F6432S does not support the OCD function. MC96F6432 should be used for debugging.OCD connector diagram: Connect OCD with user system12 User VCC3 45 67 8User GNDDSCLDSDA910Figure 1.1debugger and pin descriptionSubject MC96F6432S MC96F6432 (Evaluation chip)Internal LCD bias dividing resistor(Chapter 11.15 – LCD driver)Full-flash erase mode method(Chapter 15 – Flash memory)60kΩ and 120kΩ selectableAdded the IRSEL bit in the LCDCRL registerAdded LCD contrast formula with 120kΩSector erase mode60k onlySector and byte erase modeTable 1.2Difference between MC96F6432S and evaluation chip (MC96F6432)5
