10.2
This section lists all inputs to the ADC12B16C block.
10.2.1
10.2.1.1
This pin serves as the analog input Channel x. It can also be configured as digital port or external trigger
for the ATD conversion.
10.2.1.2
These inputs can be configured to serve as an external trigger for the ATD conversion.
Refer to device specification for availability and connection of these inputs!
