4.8.1 FLASH Block Protect Register
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
Non-volatile FLASH register; write by programming.
Address:
The FLASH 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.

Write:
Start address of FLASH block protect
BPR[7:0] represent bits [14:7] of a 16-bit memory address. Bits
[15:14] are logic 1’s and bits [6:0] are logic 0’s.
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 or $XX80 (at
page boundaries — 128 bytes) within the FLASH memory.
Examples of protect start address is shown in
