13.0
The analog-to-digital (A/D) converter module has five
inputs for the PIC16C72/73/73A/76, and eight for the
PIC16C74/74A/77.
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.
The A/D module has three registers. These registers
are:
The ADCON0 register, shown in Figure 13-1, controls
the operation of the A/D module. The ADCON1 regis-
ter, shown in Figure 13-2, configures the functions of
the port pins. The port pins can be configured as ana-
log inputs (RA3 can also be a voltage reference) or as
digital I/O.
