These values for DEV<10:3> may be shared with other devices. The specific device is always identified
by using the entire DEV<10:0> bit sequence.
DEV<2:0>: Device ID bits
010 = PIC18F45K20
011 = PIC18F25K20
100 = PIC18F44K20
101 = PIC18F24K20
110 = PIC18F43K20
111 = PIC18F23K20
REV<4:0>: Revision ID bits
These bits are used to indicate the device revision.
DEV<10:3>: Device ID bits
These bits are used with the DEV<2:0> bits in the Device ID Register 1 to identify the
part number.
