Capacitive Sense (CSEN) Peripheral API.
This module provides functions for controlling the capacitive sense peripheral of Silicon Labs 32-bit MCUs and SoCs. The CSEN includes a capacitance-to-digital circuit that measures capacitance on selected inputs. Measurements are performed using either a successive approximation register (SAR) or a delta modulator (DM) analog to digital converter.
The CSEN can be configured to measure capacitance on a single port pin or to automatically measure multiple port pins in succession using scan mode. Also several port pins can be shorted together to measure the combined capacitance.
The CSEN includes an accumulator which can be configured to average multiple conversions on the selected input. Additionally, an exponential moving average (EMA) calculator is included to provide data smoothing. A comparator is also included and can be used to terminate a continuous conversion when the configured threshold condition is met.
The following example shows how to intialize and start a single conversion on one input:

To manually start a conversion use CSEN_Start(). To check if a conversion is in progress use CSEN_IsBusy(), or alternatively use the interrupt flags returned by CSEN_IntGet() to detect when a conversion is completed.
