2.6.2.2 FLASH-1 Block Protect Register
The FLASH-1 block protect register (FL1BPR) is implemented as a byte within the FLASH-1 memory;
therefore, it can only be written during a FLASH programming sequence. The value in this register
determines the starting location of the protected range within the FLASH-1 memory.
FL1BPR[7:0] — Block Protect Register Bits 7 to 0
Decreasing the value in FL1BPR by one increases the protected range by one page (128 bytes).
However, programming the block protect register with $FE protects a range twice that size, 256 bytes, in
the corresponding array. $FE means that locations $FF00–$FFFF are protected in FLASH-1.
The FLASH memory does not exist at some locations. The block protection range configuration is
unaffected if FLASH memory does not exist in that range. Refer to
desired locations are protected.
Freescale Semiconductor
These eight bits represent bits [14:7] of a 16-bit memory address. Bit 15 is a 1 and bits [6:0] are 0s.
The resultant 16-bit address is used for specifying the start address of the FLASH-1 memory for block
protection. FLASH-1 is protected from this start address to the end of FLASH-1 memory at $FFFF.
With this mechanism, the protect start address can be $XX00 and $XX80 (128 byte page boundaries)
within the FLASH-1 array.
Address: $FF80
