T89C51CC01 UART Bootloader
The 4 MSB of the Hardware Byte can be read/written by software (this area is called Fuse bits).
The 4 LSB can only be read by software and written by hardware in parallel mode (with parallel
programmer devices).
Note:
The bootloader has Software Security Byte (SSB) to protect itself from user access 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.
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, BSB and SBV.
The Bootloader returns an error message.
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 error message.
