PIC18F8723 FAMILY
3.0 SPECIAL FEATURES OF THE
CPU
Note:
For additional details on the Configuration
bits, refer to Section 25.1 “Configuration
Bits” in the “PIC18F8722 Family Data
Sheet” (DS39646). Device ID information
presented in this section is for the
PIC18F8723 family only.
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.
