Analog-to-digital converter (ADC)

17.1

Introduction

ADC is a 12bit analog-to-digital converter. It has up to 9 multiplexed channels allowing it to
measure signals from 8 externals and 1 internal source.
ADC of various channels can be performed in single mode. The result of the ADC is stored in
12 bit register.
