12.0. A/D Converter Test Inputs
An A/D converter is used for converting an analog signal into the appropriate digital value. A/D converter is linear, which means that
converted number is linearly dependent on the input voltage value. The A/D converter built into the microcontroller converts an analog
voltage value into a 10-bit number. Potentiometer P5 enables voltage to vary between 0 and 5V. The microcontroller with a built-in
A/D converter is supplied with this voltage via test inputs. Jumper J15 is used for selecting one of the following pins PF0, PF1, PF2

In order to enable the microcontroller to accurately perform A/D conversion, it is necessary to turn off LEDs and
pull-up/pull-down resistors on the port pins used by the A/D converter.
