The analog-to-digital (A/D) converter module has five
input channels.
The A/D allows conversion of an analog input signal to
a corresponding 8-bit digital number (refer to Applica-
tion Note AN546 for use of A/D Converter). The output
of the sample and hold is the input into the converter,
which generates the result via successive approxima-
tion. The analog reference voltage is software select-
able to either the device’s positive supply voltage (V
or the voltage level on the RA3/AN3/V
The A/D converter has the feature of being able to
operate while the device is in SLEEP mode. To operate
in sleep, the A/D conversion clock must be derived from
the A/D’s internal RC oscillator.

GO/DONE: A/D Conversion Status bit
If ADON = 1
1 = A/D conversion in progress (setting this bit starts the A/D conversion)
0 = A/D conversion not in progress (This bit is automatically cleared by hardware when the A/D
conversion is complete)
Unimplemented: Read as '0'
ADON: A/D On bit
1 = A/D converter module is operating
0 = A/D converter module is shutoff and consumes no operating current

Additional information on the A/D module is available in
the
(DS33023).
The A/D module has three registers. These registers
are:
A device reset forces all registers to their reset state.
This forces the A/D module to be turned off, and any
conversion is aborted.
The ADCON0 register, shown in Figure 9-1, controls
the operation of the A/D module. The ADCON1 regis-
ter, shown in Figure 9-2, configures the functions of the
port pins. The port pins can be configured as analog
inputs (RA3 can also be a voltage reference) or as dig-
ital I/O.
