16.0
The
conversion of an analog input signal to a 12-bit digital
number. This module is based on a Successive
Approximation
provides a maximum sampling rate of 200 ksps. The
ADC module has up to 10 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 selectable to either the
device supply voltage (AV
on the (V
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:
• A/D Control Register 1 (ADCON1)
• A/D Control Register 2 (ADCON2)
• A/D Control Register 3 (ADCON3)
• A/D Input Select Register (ADCHS)
• A/D Port Configuration Register (ADPCFG)
• A/D 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.
