LOCK — Lock Register Bit
This register controls the operation of the Flash EEPROM array. BOOTP
cannot be changed when the LOCK control bit in the FEELCK register is
set or if HVEN or PGM or ERAS in the FEECTL register is set .
BOOTP — Boot Protect
This register controls the programming and erasure of the Flash
EEPROM.
In normal modes the LOCK bit can only be written once after reset.
The boot blocks are located at $6000–$7FFF and $E000–$FFFF for
each Flash EEPROM module.
