x = unknown, u = unchanged, - = unimplemented. Shaded cells are unimplemented, read as ‘0’.
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.
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.
This bit should always be maintained as ‘0’.
Implemented in 80-pin devices only.
See Register 23-7 and Register 23-8 for DEVID values. These registers are read-only and cannot be programmed by
the user.
