1.3.1 Compiler
ABOV Semiconductor does not provide compiler. It is recommended that you consult a compiler provider.
The MC96F6432Acore is Mentor 8051 and the ROM size is smaller than 64 Kbytes. 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. MC96F6432A does not support the OCD function. MC96F6432 should be used for debugging.
2. Do not access to P0, P1, P2, P3, P4, P5 and EIFLAG0 registers through the “direct bit test and branch
instructions” in the MC96F6432. Refer to the “MC96F6432 User’s Manual”.

1.4 MTP programming
1.4.1 Overview
The program memory of MC96F6432A is MTP Type. This flash is accessed by serial data format. There are four
pins(DSCL, DSDA, VDD and VSS) for programming/reading the flash.
Table 1.3 Descriptions of pins which are used to programming/reading the Flash
1.4.2 On-Board programming
The MC96F6432A needs only four signal lines including VDD and VSS pins for programming FLASH with serial
communication protocol. Therefore the on-board programming is possible if the programming signal lines are ready at
the PCB of application board is designed.
1.4.2.1 Circuit Design Guide
At the FLASH programming, the programming tool needs 4 signal lines that are DSCL, DSDA, VDD and VSS. When
you design the PCB circuits, you should consider the usage of these signal lines for the on-board programming.
Please be careful to design the related circuit of these signal pins because rising/falling timing of DSCL and DSDA is
very important for proper programming.

NOTE) 1. In on-board programming mode, very high-speed signal will be provided to pin DSCL and DSDA.
And it will cause some damages to the application circuits connected to DSCL or DSDA port if the
application circuit is designed as high speed response such as relay control circuit. If possible, the
I/O configuration of DSDA, DSCL pins had better be set to input mode.
2. The value of R1 and R2 is recommended value. It varies with circuit of system.
