The
conversion of an analog input signal to a 10-bit binary
representation of that signal. The PIC12F675 has four
analog inputs, multiplexed into one sample and hold
FIGURE 7-1:

There are two registers available to control the
functionality of the A/D module:

7.1.1
The ANS3:ANS0 bits (ANSEL<3:0>) and the TRISIO
bits control the operation of the A/D port pins. Set the
corresponding TRISIO bits to set the pin output driver
to its high-impedance state. Likewise, set the
corresponding ANS bit to disable the digital input
buffer.
7.1.2
There are four analog channels on the PIC12F675,
AN0
(ADCON0<3:2>) control which channel is connected to
the sample and hold circuit.
7.1.3
There are two options for the voltage reference to the
A/D converter: either V

A/D Configuration and Operation
Analog voltages on any pin that is defined
as a digital input may cause the input
