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.
0010 0000 = PIC18F2XK20/4XK20 devices
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.
