*
* @brief ACMP example for XMC1300
*
* In this example, ACMP1 slice is configured to receive VRef/2 on its IN-P pad.
* Connect VDD to pin P2.11.
* Bit field CMP_OUT of register ANACMP1 changes its state based on the input applied on IN-N pad.
*
* History <br>
*
* Version 1.0.0 Initial <br>
* Version 1.0.2 a. Updated for changes in the ACMP LLD (Version 2.0.0).
* b. Explicit call to enable comparator is added<br>
* c. Corrected g_acmp_config structure hysteresis element mistake<br>
