Preface

To configure STC8H3k64S4 The built-in EEPROM.

One 、EEPROM Size and address

I'm using STC8H3k64S4, Inside EEPOM Yes 64k size , Use IAP Way to operate .IAP The way can be right EEPROM Carry out reading 、 Write 、 Erase operation . From the diagram , Address from 0x0000h To 0xFFFFh.

The erase operation is performed in sectors , Per sector 512 byte , That is, each time the erase command is executed, a sector will be erased , Both read data and write data are operated in bytes , That is, each time a read or write command is executed, only one byte can be read or written .

This model can use STC_ISP Set up EEPROM size .

Two 、EEPROM To configure

I need to store the voltage protection range , Current protection range , Power protection range . Each item has 2 Parameters , In order not to cause misoperation （ Erase sectors , Delete what you don't want to delete ）, Set up 6 Sectors . Therefore, the EE2PROM Set to 3k size .

summary

Basic hardware operation program design , Just refer to the official manual .
