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 programmed to ‘1’. This ensures that the location is executed as a NOP if it
is accidentally executed.
3: See Register 27-9 and Register 27-10 for DEVID values. These registers are read-only and cannot be programmed by the user.
