The flow described below allows the user to erase the Flash memory.
Two modes of Flash erasing are possible:
•
•
The Full Chip erase command erases the whole Flash (64 Kbytes) and sets some Configuration
Bytes at their default values:
•
•
•
The full chip erase is always executed whatever the Software Security Byte value is.
The Block erase command erases only a part of the Flash.
Three Blocks are defined in the AT89C51CC03:
•
•
Full Chip erase
Block erase
BSB = FFh
SBV = FCh
SSB = FFh (NO_SECURITY)
block0 (From 0000h to 1FFFh)
block1 (From 2000h to 3FFFh)
