8.0
The Analog-to-Digital (A/D) Converter module has four
inputs.
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 a unique 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

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 8-1, controls
the operation of the A/D module. The ADCON1 regis-
ter, shown in Figure 8-2, 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
digital I/O.
