DEV2:DEV0: Device ID bits
These bits are used with the DEV<10:3> bits in the Device ID Register 2 to identify the
part number.
000 = PIC18F248
001 = PIC18F448
010 = PIC18F258
011 = PIC18F458
REV4:REV0: Revision ID bits
These bits are used to indicate the device revision.
Legend:
R = Readable bit
P = Programmable bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state
