FL2BPR[7:0] — Block Protect Register Bit 7 to Bit 0
FLASH-2 Protected Ranges:
Freescale Semiconductor
These eight bits represent bits [14:7] of a 16-bit memory address. Bit 15 is logic 1 and bits [6:0] are
logic 0s.
The resultant 16-bit address is used for specifying the start address of the FLASH-2 memory for block
protection. FLASH-2 is protected from this start address to the end of FLASH-2 memory at $7FFF.
With this mechanism, the protect start address can be $XX00 and $XX80 (128 byte page boundaries)
within the FLASH-2 array.
Address:
The FLASH-2 Block Protect Register (FL2BPR) controls the block
protection for the FLASH-2 array. However, FL2BPR is implemented within
the FLASH-1 memory array and therefore, the FLASH-1 Control Register
(FL1CR) must be used to program/erase FL2BPR.
