DEV10:DEV3: Device ID bits(1)
These bits are used with the DEV2:DEV0 bits in Device ID Register 1 to identify the part number.
0000 1100 = PIC18F2525/2620/4525/4620 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.
