* @brief Analog comparator (ACMP) Peripheral API
*
* @details
* The Analog Comparator is used to compare the voltage of two analog inputs,
* with a digital output indicating which input voltage is higher. Inputs can
* either be one of the selectable internal references or from external pins.
* Response time and thereby also the current consumption can be configured by
* altering the current supply to the comparator.
*
* The ACMP is available down to EM3 and is able to wakeup the system when
* input signals pass a certain threshold. Use @ref ACMP_IntEnable to enable
* an edge interrupt to use this functionality.
*
* Here is an example of how to use the em_acmp.h API for comparing an input
* pin to an internal 2.5V reference voltage.
*
* @if DOXYDOC_P1_DEVICE
* @include em_acmp_compare_p1.c
* @endif
*
* @if DOXYDOC_P2_DEVICE
* @include em_acmp_compare_p2.c
* @endif
*
* @note
* The ACMP can also be used to compare two separate input pins.
*
* @details
* The ACMP also contains specialized hardware for capacitive sensing. This
* module contains the function @ref ACMP_CapsenseInit for initializing the
* ACMP for capacitive sensing and the function @ref ACMP_CapsenseChannelSet
* for selecting the current capsense channel.
*
* For applications that require capacitive sensing it is recommended to use a
* library like cslib which is provided by Silicon Labs.
