-n = Value when device is unprogrammed u = Unchanged from programmed state
bit 7-0 DEV10:DEV3: Device ID bits
These bits are used with the DEV2:DEV0 bits in the Device ID Register 1 to identify the
part number.
0000 0101 = PIC18F2220/2320/4220/4320 devices
Note 1: These values for DEV10:DEV3 may be shared with other devices. The specific device is always identified
by using the entire DEV10:DEV0 bit sequence.
