Chapter 44 A/D Converter
6.Q & A
* Analogue input channels AN14 and AN15 can be also used as D/A converter outputs. In case of exclusive A/D converter
usage do not enable the D/A converter output with DACR.DAE[1:0] since this has priority over A/D converter input. See
chapter “
D/A Converter (Page No.909) ” for further information about D/A converter.
6.5 How do I enable analog pin input for Stepper Motor Controller?
Use Port Function register PFR and Extra Port Function register EPFR.
See chapter “ Stepper Motor Controller (Page No.871) ” about using the A/D converter for SMC operation.
6.6 To select how to activate the A/D converter
There are three types of activation triggers:
• Software trigger
• Reload timer rising signal
• External trigger input falling signal
To set an activation trigger, use Activation Trigger Selection bits (ADCS.STS[1: 0]).
