4.2
This section lists all inputs to the ATD10B16C block.
4.2.1
This pin serves as the analog input channel x. It can also be configured as general-purpose digital input
and/or external trigger for the ATD conversion.
4.2.2
These inputs can be configured to serve as an external trigger for the ATD conversion.
