4.3.2 FLASH Block Protect Register
MC68HC908MR8 — Rev 4.1
Freescale Semiconductor
The block protect register (FLBPR) is implemented as a byte within the
FLASH memory, and therefore can only be written during a
programming sequence of the FLASH memory. The value in this register
determines the starting location of the protected range within the FLASH
memory.

Ad-
These eight bits represent bits [13:6] of a 16-bit memory address.
Bits[15:14] are logical 1s and bits [5:0] are logic 0s.
The resultant 16-bit address is used for specifying the start address
of the FLASH memory for block protection. The FLASH is protected
from this start address to the end of FLASH memory at $FFFF. With
this mechanism, the protect start address can be $XX00, $XX40,
$XX80, and $XXC0 (64-byte page boundaries) within the FLASH
memory.
$FF7E
U= Unaffected by reset. Initial value from factory is 1.
Write to this register by a programming sequence to the FLASH memory.
