SPECIAL FEATURES OF THE
CPU
x = unknown, u = unchanged, — = unimplemented. Shaded cells are unimplemented, read as ‘0’.
DEVID registers are read-only and cannot be programmed by the user.
See Register 3-1 and Register 3-2 for DEVID1 and DEVID2 values.
For additional details on the Configuration
bits, refer to Section 23.1 “Configuration
Bits” in the “PIC18F2420/2520/4420/4520
Data Sheet” (DS39631). Device ID informa-
tion presented in this section is for the
PIC18F2423/2523/4423/4523 devices only.
DEV<3:0>: Device ID bits
1101 = PIC18F4423
1001 = PIC18F4523
0101 = PIC18F2423
0001 = PIC18F2523
REV<3:0>: Revision ID bits
These bits are used to indicate the device revision.

The Device ID registers are read-only registers. They
identify the device type and revision for device pro-
grammers and can be read by firmware using table
reads.
