8.3 A/D CONVERTER (ADC)
8.3.1 Introduction
The on-chip Analog to Digital Converter (ADC) pe-
ripheral is a 8-bit, successive approximation con-
verter. This peripheral has multiplexed analog in-
put channels (refer to device pin out description)
that allow the peripheral to convert the analog volt-
age levels from different sources.
The result of the conversion is stored in a 8-bit
Data Register. The A/D converter is controlled
through a Control Register.
