bit 7
DEV<2:0>: Device ID bits
These bits are used with the DEV<10:3> bits in the Device ID register 2 to identify the part
number.
000 = PIC18F4331
001 = PIC18F4431
100 = PIC18F2331
101 = PIC18F2431
REV<4:0>: Revision ID bits
These bits are used to indicate the device revision.
bit 7
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
