The Analog-to-Digital (A/D) Converter module has
10 inputs for the 28-pin devices and 13 for the 44-pin
devices. Additionally, two internal channels are available
for sampling the V
voltage. 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)

CONVERTER (A/D) MODULE
These channels are not implemented on 28-pin devices.
Performing a conversion on unimplemented channels will return random values.
For best accuracy, the band gap reference circuit should be enabled (ANCON1<7> = 1) at least 10 ms
before performing a conversion on this channel.

• A/D Port Configuration Register 2 (ANCON0)
• A/D Port Configuration Register 1 (ANCON1)
• A/D Result Registers (ADRESH and ADRESL)
The ADCON0 register, in Register 20-1, controls the
operation of the A/D module. The ADCON1 register, in
Register 20-2, configures the A/D clock source,
programmed acquisition time and justification.
The ANCON0 and ANCON1 registers, in Register 20-3
and Register 20-4, configure the functions of the port
pins.
