Information
4208D–CAN–03/08
Several types of APIs are available:
•
•
•
•
•
All routines to access EEPROM Data are managed directly from the application without using
bootloader resources.
The bootloader is not used to read the Flash memory.
For more details on these routines see the T89C51CC02 datasheet sections “Program/Code
Memory” and “EEPROM Data Memory”.
Two routines are available to program the Flash:
•
