ROM Code Protect bits prevent reading or rewriting of the on-chip flash memory when using a parallel programmer.

Flash Memory ID Code protection feature prevents unauthorized access. The multi-byte ID sent by the serial programmer must match the ID previously set by the user in order to access the flash memory.

Data Protect Function to enable and disable programming or erasing of each flash memory block.

Programmer Mode: MCUs can be programmed using an external box such as a parallel programmer or debug emulator.

Boot Mode: Built-in boot loader program allows PC connection through RS232 interface for easy programming.

CPU/User Mode: Customer can develop custom bootloader program to rewrite the flash memory. The rewrite program can be transferred to RAM when all flash memory contents need to be changed.Trusted & Flexible
