void ACMP_CapsenseChannelSet (ACMP_TypeDef *acmp, ACMP_Channel_TypeDef channel)
 Sets the ACMP channel used for capacative sensing.
void ACMP_CapsenseInit (ACMP_TypeDef *acmp, const ACMP_CapsenseInit_TypeDef *init)
 Sets up the ACMP for use in capacative sense applications.
void ACMP_ChannelSet (ACMP_TypeDef *acmp, ACMP_Channel_TypeDef negSel, ACMP_Channel_TypeDef posSel)
 Sets which channels should be used in ACMP comparisons.
void ACMP_Disable (ACMP_TypeDef *acmp)
 Disables the ACMP.
void ACMP_Enable (ACMP_TypeDef *acmp)
 Enables the ACMP.
void ACMP_GPIOSetup (ACMP_TypeDef *acmp, uint32_t location, bool enable, bool invert)
 Sets up GPIO output from the ACMP.
void ACMP_Init (ACMP_TypeDef *acmp, const ACMP_Init_TypeDef *init)
