21.0
The Analog-to-Digital (A/D) Converter module has
8 inputs for the 64-pin devices and 12 for the 80-pin
devices. This module allows conversion of an analog
input signal to a corresponding 10-bit digital number.
The module has six registers:
• A/D Control Register 0 (ADCON0)
• A/D Control Register 1 (ADCON1)
