21.0
The Analog-to-Digital (A/D) Converter module has
11 inputs for the 64-pin devices and 15 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)

• A/D Port Configuration Register 2 (ANCON0)
• A/D Port Configuration Register 1 (ANCON1)
• A/D Result Registers (ADRESH and ADRESL)
The ADCON0 register, shown in Register 21-1,
controls the operation of the A/D module. The
ADCON1 register, shown in Register 21-2, configures
the A/D clock source, programmed acquisition time and
justification.
