* Refer to description of parameters or to reference manual. | |
* @note On this STM32 serie, scaler bridge is configurable: | |
* to optimize power consumption, this function enables the | |
* voltage scaler bridge only when required | |
* (when selecting comparator input based on VrefInt: VrefInt or | |
* subdivision of VrefInt). | |
* - For scaler bridge power consumption values, | |
* refer to device datasheet, parameter "IDDA(SCALER)". | |
* - Voltage scaler requires a delay for voltage stabilization. | |
* Refer to device datasheet, parameter "tSTART_SCALER". | |
* - Scaler bridge is common for all comparator instances, | |
* therefore if at least one of the comparator instance | |
* is requiring the scaler bridge, it remains enabled. | |
