Full Chip Erase
Checksum Error
4289C–8051–11/05
The ISP command "Full Chip Erase" erases all User Flash memory (fills with FFh) and
sets some bytes used by the bootloader at their default values:
•
•
•
The Full Chip Erase does not affect the bootloader.
When a checksum error is detected send ‘X’ followed with CR&LF.
BSB = FFh
SBV = FCh
SSB = FFh and finally erase the Software Security Bits
