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
110 = PIC18F4420
100 = PIC18F4520
010 = PIC18F2420
000 = PIC18F2520
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 Device ID Register 1 to identify the part number.
