The10-bit high-speed Analog-to-Digital Converter
(ADC) allows conversion of an analog input signal to a
10-bit digital number. This module is based on a Suc-
cessive Approximation Register (SAR) architecture,
and provides a maximum sampling rate of 1 Msps. The
ADC module has 16 analog inputs which are multi-
plexed into four sample and hold amplifiers. The output
of the sample and hold is the input into the converter,
which generates the result. The analog reference volt-
ages are software selectable to either the device sup-
ply voltage (AV
(V
being able to operate while the device is in Sleep
mode.

The ADC module has six 16-bit registers:
• A/D Control Register1 (ADCON1)
• A/D Control Register2 (ADCON2)
• A/D Control Register3 (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 block diagram of the A/D module is shown in
Figure 21-1.

The
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.
