Flash Sector Protect Register
The Flash Sector Protect Register, shown in Table 119, protects Flash memory sectors
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).
