from being programmed or erased from user code. The Flash Sector Protect Register
shares its Register File address with the Flash Page Select Register. The Flash Sector pro-
tect Register can be accessed only after writing the Flash Control Register with 5Eh.
User code can only write bits in this register to 1 (bits cannot be cleared to 0 by user code).
