In normal modes the LOCK bit can only be written once after reset.
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 ENPE in the FEECTL register is set.
BOOTP — Boot Protect
In normal mode, writes to FEETST control bits have no effect and always
read zero. The Flash EEPROM module cannot be placed in test mode
inadvertently during normal operation.

The boot block is located at $7800–$7FFF or $F800–$FFFF
depending upon the mapped location of the Flash EEPROM array
and mask set ($7C00–$7FFF or $FC00–$FFFF for 1K byte block).
