Legend: x = unknown, u = unchanged, - = unimplemented. Shaded cells are unimplemented, read as ‘0’.
Note 1: Values reflect the unprogrammed state as received from the factory and following Power-on Resets. In all other Reset
states, the configuration bytes maintain their previously programmed states.
2: The value of these bits in program memory should always be ‘1’. This ensures that the location is executed as a NOP if it
is accidentally executed.
3: This bit should always be maintained as ‘0’.
4: Implemented in 80-pin devices only. On 64-pin devices, these bits are reserved and should always be maintained as ‘1’.
5: See Register 24-7 and Register 24-8 for DEVID values. These registers are read-only and cannot be programmed by
the user.
