The Analog-to-Digital (A/D) converter module has four
analog 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
The A/D converter has a unique feature of being able
to operate while the device is in SLEEP mode.
The A/D module has three registers. These registers
are:

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 (GP1 can also be a voltage reference) or as
digital I/O.
