The protected range is:
Decreasing the value in the FLxBPR by one increases the protected
range by one page (128 bytes). However, programming the block protect
register with $FE protects a range twice that size, 256 bytes, in the
corresponding array. $FE means that locations $FF00–$FFFF or
$7F00–$7FFF are protected in FLASH-1 or FLASH-2, respectively.
The FLASH memory does not exist at some locations. The block
protection range is unaffected if FLASH memory does not exist in that
range. Refer to the memory map and make sure that the desired
locations are protected.
