Figure 4-7 FLASH Protection Register (FPROT)
FPOPEN — Open Unprotected FLASH for Program/Erase
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).
FPDIS — FLASH Protection Disable
1 = No FLASH block is protected.
0 = FLASH block specified by FPS2:FPS0 is block protected (program and erase not allowed).
FPS2:FPS1:FPS0 — FLASH Protect Size Selects
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 Table 4-8). Protected FLASH locations cannot be erased or
programmed.

NOTES:
1. No redirection if FPOPEN = 0, or FNORED = 1.
2. Reset vector is not redirected.
3. Use for 60K version only. When protecting all of 32K version memory, use FPOPEN = 0.
