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.

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.
