1.4 MTP programming
1.4.1 Overview
The program memory of MC97F60128 is MTP Type. This flash is accessed by serial data format. There are five
pins(DSCL, DSDA, RUNFLAG, VDD, VSS) for programming/reading the flash.
Table 1.2 Descriptions of pins which are used to programming/reading the Flash
1.4.2 On-Board programming
The MC97F60128 needs only five signal lines including VDD and VSS pins for programming FLASH with serial
protocol. Therefore the on-board programming is possible if the programming signal lines are considered when the
PCB of application board is designed.
