AT89C5132
The bootloader has Software Security Byte (SSB see
or ISP access.
The Software Security Byte (SSB) protects from ISP accesses. The command ’Program Soft-
ware Security Bit’ can only write a higher priority level. There are three levels of security:
•
•
•
Only a full chip erase command can reset the software security bits.

Blank Check
Level 0: NO_SECURITY (FFh)
This is the default level.
From level 0, one can write level 1 or level 2.
Level 1: WRITE_SECURITY (FEh)
In this level it is impossible to write in the Flash memory.
The Bootloader returns an err_WRITE status.
From level 1, one can write only level 2.
Level 2: RD_WR_SECURITY (FCh)
Level 2 forbids all read and write accesses to/from the Flash memory.
The Bootloader returns an err_WRITE or an err_VENDOR status.
