The 12-bit Analog-to-Digital Converter (ADC) allows
conversion of an analog input signal to a 12-bit digital
number. This module is based on a Successive
Approximation Register (SAR) architecture and pro-
vides a maximum sampling rate of 200 ksps. The ADC
module has up to 16 analog inputs which are multi-
plexed into a sample and hold amplifier. The output of
the sample and hold is the input into the converter
which generates the result. The analog reference volt-
age is software selectable to either the device supply
voltage (AV
(V
being able to operate while the device is in Sleep mode
with RC oscillator selection.

The ADC module has six 16-bit registers:
• ADC Control Register 1 (ADCON1)
• ADC Control Register 2 (ADCON2)
• ADC Control Register 3 (ADCON3)
• ADC Input Select Register (ADCHS)
• ADC Port Configuration Register (ADPCFG)
• ADC Input Scan Selection Register (ADCSSL)
The ADCON1, ADCON2 and ADCON3 registers con-
trol the operation of the ADC module. The ADCHS reg-
ister selects the input channels to be converted. The
ADPCFG register configures the port pins as analog
inputs or as digital I/O. The ADCSSL register selects
inputs for scanning.

The SSRC<2:0>, ASAM, SMPI<3:0>,
BUFM and ALTS bits, as well as the
ADCON3 and ADCSSL registers, must
not be written to while ADON = 1. This
would lead to indeterminate results.
