Memory
2.6.6 FLASH Block Protect Register
The FLASH block protect register 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 address of the protected range within the FLASH memory.
Address:
$FFBE
Bit 7
Read:
BPR7
Write:
Reset:
Write to this register is by a programming sequence to the FLASH memory.
Figure 2-5. FLASH Block Protect Register (FLBPR)
BPR[7:0] — FLASH Protection Register Bits [7:0]
These eight bits in FLBPR represent bits [13:6] of a 16-bit memory address. Bits [15:14] are 1s and
bits [5:0] are 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, or XXC0 within the FLASH
memory. See
