Analog-to-Digital Converter (S08ADC12V1)
APCTL1=0x02
APCTL2=0x00
10.6
This section contains information for using the ADC module in applications. The ADC has been designed
to be integrated into a microcontroller for use in embedded control applications requiring an A/D
converter.
10.6.1
The following sections discuss the external pins associated with the ADC module and how they must be
used for best results.
