DEV2:DEV0: Device ID bits
011 = PIC18F4XJ10
010 = PIC18F2XJ10
001 = PIC18F4XJ10
000 = PIC18F2XJ10
Note: Where values for DEV2:DEV0 are shared by more than one device number, the
specific device is always identified by using the entire DEV10:DEV0 bit sequence.
bit 4-0 REV4:REV0: Revision ID bits
These bits are used to indicate the device revision.
Legend:
R = Read-only bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state

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.
0001 1100 = PIC18FX5J10 devices
0001 1101 = PIC18FX4J10 devices
Note: The values for DEV10:DEV3 may be shared with other device families. The specific
device is always identified by using the entire DEV10:DEV0 bit sequence.
Legend:
R = Read-only bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state
