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.

1.4 MTP programming

1.4.1 Overview

The program memory of MC96F6432S 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 MC96F6432S 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 areDSCL, 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.
