11.0
The analog-to-digital (A/D) converter module has six
inputs for the PIC16C773 and ten for the PIC16C774.
The analog-to-digital converter (A/D) allows conver-
sion of an analog input signal to a corresponding
12-bit digital number. The A/D module has up to 10
analog inputs, which are multiplexed into one sample
and hold. The output of the sample and hold is the
input into the converter, which generates the result via
successive approximation. The analog reference volt-
ages are software selectable to either the device’s
analog
(AV
V
(VRH, VRL).
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 four 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 operation of the A/D module. The ADCON1 regis-
ter, shown in
the port pins, the voltage reference configuration and
the result format. The port pins can be configured as
analog inputs or as digital I/O.
The combination of the ADRESH and ADRESL regis-
ters contain the result of the A/D conversion. The reg-
ister pair is referred to as the ADRES register. When
the A/D conversion is complete, the result is loaded
into
