* @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.

|
|
* 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>
