32.5.3 Analog-to-Digital Converter (ADC)

The PTC utilizes the in-built 10-bit ADC for signal acquisition and conversion. The ADC must be enabled and configured appropriately to allow the correct behavior of the PTC, which is managed by the MCC Touch library. Refer to the Analog-to-Digital Converter (ADC) section for further details.

When the PTC is enabled, it takes control of ADC. The MCC Touch library provides APIs to facilitate multiplexing of the ADC between the PTC and non-touch applications if the application also requires the ADC for purposes other than touch sensing.

When the PTC is disabled, the ADC becomes available for normal operation.
