DEV<2:0>: Device ID bits
Devices with DEV<10:3> of 0101 0010 (see DEVID2):
010 = PIC18F65K22
000 = PIC18F66K22
101 = PIC18F85K22
011 = PIC18F86K22
Devices with DEV<10:3> of 0101 0001:
000 = PIC18F67K22
010 = PIC18F87K22
REV<4:0>: Revision ID bits
These bits are used to indicate the device revision.

DEV<10:3>: Device ID bits⁽¹⁾
These bits are used with the DEV<2:0> bits in the Device ID Register 1 to identify the part number.
0101 0010 = PIC18F65K22, PIC18F66K22, PIC18F85K22 and PIC18F86K22
0101 0001 = PIC18F67K22 and PIC18F87K22
Note 1: 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.
