$00F5/$00F9
This register controls the operation of the Flash EEPROM array. BOOTP
cannot be changed when the LOCK control bit in the FEExxLCK register
is set or if ENPE in the FEExxCTL register is set.
BOOTP — Boot Protect
The boot blocks are located at $6000–$7FFF and $E000–$FFFF for
each Flash EEPROM module.
0 = Enable erase and program of 8K byte boot block
1 = Disable erase and program of 8K byte boot block
