4.6.4
During reset, the contents of the nonvolatile location NVPROT is copied from FLASH into FPROT. This
register may be read at any time, but user program writes have no meaning or effect. Background debug
commands can write to FPROT.
4.6.5
Bits 3, 1, and 0 always read 0 and writes have no meaning or effect. The remaining five bits are status bits
that can be read at any time. Writes to these bits have special meanings that are discussed in the bit
descriptions.
Freescale Semiconductor
Background commands can be used to change the contents of these bits in FPROT.

FLASH Protect Select Bits — When FPDIS = 0, this 7-bit field determines the ending address of unprotected
FLASH locations at the high address end of the FLASH. Protected FLASH locations cannot be erased or
programmed.
FLASH Protection Disable
0 FLASH block specified by FPS[7:1] is block protected (program and erase not allowed).
1 No FLASH block is protected.
