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 (32 Kbytes) and sets some Configuration
Bytes at their default values:
•
•
•
The full chip erase is always executed whatever the Software Security Byte value is.
Note:
The Block erase command erases only a part of the Flash.
Three Blocks are defined in the T89C51CC01:
•
•
•
As the Program Configuration Information flows, the erase block command has three possible
answers:
•
•
•
Full Chip erase
Block erase
BSB = FFh
SBV = FCh
SSB = FFh (NO_SECURITY)
block0 (From 0000h to 1FFFh)
block1 (From 2000h to 3FFFh)
block2 (From 4000h to 7FFFh)
‘.’ & ‘CR’ & ’LF’ when the data are programmed
‘X’ & ‘CR’ & ‘LF’ if the checksum is wrong
‘P’ & ‘CR’ & ‘LF’ if the Security is set
Erase block2 (16k to 32k)
Erase block1 (8k to 16k)
Erase block0 (0k to 8k)

Take care that the full chip erase execution takes few seconds (256 pages )
