FPOPEN — Open Unprotected FLASH for Program/Erase
FPDIS — FLASH Protection Disable
FPS2:FPS1:FPS0 — FLASH Protect Size Selects
Freescale Semiconductor
No redirection if FPOPEN = 0, or FNORED = 1.
Reset vector is not redirected.
32K and 60K devices only.
60K devices only.
FPS2:FPS1:FPS0

When FPDIS = 0, this 3-bit field determines the size of a protected block of FLASH locations at the
high address end of the FLASH (see
programmed.
Background commands can be used to change the contents of these bits in FPROT.
1 = Any FLASH location, not otherwise block protected or secured, may be erased or programmed.
0 = Entire FLASH memory is block protected (no program or erase allowed).
1 = No FLASH block is protected.
0 = FLASH block specified by FPS2:FPS0 is block protected (program and erase not allowed).
