2.5.7 FLASH Block Protect Register
The FLASH block protect register is implemented as an 8-bit I/O register. The value in this register
determines the starting address of the protected range within the FLASH memory.
BPR[7:0] — FLASH Block Protect Bits
Freescale Semiconductor
BPR[7:1] represent bits [15:9] of a 16-bit memory address. Bits [8:0] are logic 0’s.
BPR0 is used only for BPR[7:0] = $FF, for no block protection.
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 X000, X200, X400, X0600, X800, XA00, XC00,
or XE00 (at page boundaries — 512 bytes) within the FLASH memory.
