Description
FLASH Protect Select Bits — When FPDIS = 0, this 7-bit field determines the ending address of unprotected
FLASH locations at the high address end of the FLASH. Protected FLASH locations cannot be erased or
programmed.
FLASH Protection Disable
0 FLASH block specified by FPS7:FPS1 is block protected (program and erase not allowed).
1 No FLASH block is protected.
