bit 7 bit 0

Legend:

R = Read-only bit P = Programmable bit U = Unimplemented bit, read as ‘0’

-n = Value when device is unprogrammed u = Unchanged from programmed state

bit 7-0 DEV<11:4>: Device ID bits

(1)

These bits are used with the DEV<3:0> bits in Device ID Register 1 to identify the part number.

0001 0001 = PIC18F2423/2523 devices

0001 0000 = PIC18F4423/4523 devices

Note 1: These values for DEV<11:4> may be shared with other devices. The specific device is always identified by

using the entire DEV<11:0> bit sequence.
