Part Number: TMS570LS3137

Hello! I am working with a TMS570LS3137 and I want some sectors of flash memory to be protected from erasure and overwrite. Can you please tell me where I can find the detailed information on how to protect the memory from erasure and overwrite?

Thanks a lot !

    Hello,

    1. Clearing the bit of FBSE register disables the corresponding flash sector. For example writing 0xFFFE to FBSE register, the sector 0 will not be erased and programmed.

     2. Clearing PROTL1DIS in FBPROT register will enable protection from writing to FBSE register
