The 12-bit Analog-to-Digital converter allows conver-
sion of an analog input signal to a 12-bit digital number.
This module is based on a Successive Approximation
Register (SAR) architecture and provides a maximum
sampling rate of 200 ksps. The ADC module has up to
16 analog inputs which are multiplexed 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 voltage is software select-
able to either the device supply voltage (AV
the voltage level on the (V
has a unique feature of 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
control the operation of the ADC module. The ADCHS
register 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.
