•
•
•
All routines to access EEPROM Data are managed directly from the application without using
bootloader resources.
To read the Flash memory the bootloader is not involved.
For more details on these routines see the T89C51CC01 Data sheet sections “Program/Code
Memory” and “EEPROM Data Memory”
Two routines are available to program the Flash:
