Analog-to-Digital Converter (ADC)
18.2 Introduction

18.4 Functional Description
Technical Data
312
This section describes the 10-bit analog-to-digital converter (ADC).
For further information regarding analog-to-digital converters on
Freescale microcontrollers, please consult the HC08 ADC Reference
Manual, ADCRM/AD.
Features of the ADC module include:
Depending on the package option, up to seven ADC channels are
available for sampling external sources at pins PTA6/ATD6:PT00/ATD0.
To achieve the best possible accuracy, these pins are implemented as
input-only pins when the analog-to-digital (A/D) feature is enabled. An
analog multiplexer allows the single ADC to select one of the seven ADC
channels as ADC voltage IN (ADCVIN). ADCVIN is converted by the
successive approximation algorithm. When the conversion is completed,
the ADC places the result in the ADC data register (ADRH and ADRL)
and sets a flag or generates an interrupt. See
