BPR0 is used only for BPR[7:0] = $FF, for no block protection.
The resultant 16-bit address is used for specifying the start address
of the FLASH memory for block protection. The FLASH is protected
from this start address to the end of FLASH memory, at $FFFF. With
this mechanism, the protect start address can be XX00 or XX80 (at
page boundaries — 128 bytes) within the FLASH memory.
Examples of protect start address:
and so on...
Note:
The end address of the protected range is always $FFFF.
