11.2
This section lists all inputs to the ADC10B8C block.
11.2.1
11.2.1.1
This pin serves as the analog input Channel x. It can also be configured as digital port or external trigger
for the ATD conversion.
11.2.1.2
These inputs can be configured to serve as an external trigger for the ATD conversion.
Refer to device specification for availability and connectivity of these inputs!
11.2.1.3
VRH is the high reference voltage, VRL is the low reference voltage for ATD conversion.
11.2.1.4
These pins are the power supplies for the analog circuitry of the ADC10B8C block.
