1.3 Development tools
1.3.1 Compiler
ABOV 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 the
standard 8051 compiler from other providers.
1.3.2 OCD(On-chip debugger) emulator and debugger
The OCD (On Chip Debug) emulator supports ABOV Semiconductor’s 8051 series MCU emulation.The OCD interface
uses two-wire connection between PC and MCU which is attached to user’s system. The OCD can read or change the
value of MCU internal memory and I/O peripherals. And the OCD also controls MCU internal debugging logic, it means
OCD 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 to
see more details, please refer to OCD debugger manual. You can download debugger S/W and manual from our web-
site (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.
