- n = Value at POR reset
Note:
The bit position of the configuration bits is device dependent. Please refer to the
device programming specification for bit placement. The use of a Microchip device
programmer does not require you to know the bit locations.
P = Programmable bit
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state
