PIC18F8723 FAMILY
3.0 SPECIAL FEATURES OF THE
CPU
PIC18F8723 family devices include several features
intended to maximize reliability and minimize cost
through elimination of external components. These
include:
Device ID Registers
3.1 Device ID Registers
The Device ID registers are “read-only” registers.
They identify the device type and revision to device
programmers and can be read by firmware using table
reads.
