PCNT_CntEvent_TypeDef PCNT_Init_TypeDef::auxCntEvent |
Selects whether the auxiliary counter responds to up-count events, down-count events, both or none.

PCNT_CntEvent_TypeDef PCNT_Init_TypeDef::cntEvent |
Selects whether the regular counter responds to up-count events, down-count events, both or none.

bool PCNT_Init_TypeDef::countDown |
Counting direction, only applicable for pcntModeOvsSingle and pcntModeExtSingle modes.

Referenced by PCNT_Init().
uint32_t PCNT_Init_TypeDef::counter |
Initial counter value (refer to reference manual for max value allowed). Only used for pcntModeOvsSingle (and possibly pcntModeDisable) modes. If using pcntModeExtSingle or pcntModeExtQuad modes, the counter value is reset to HW reset value.

bool PCNT_Init_TypeDef::filter |
Enable filter, only available in #pcntModeOvs* modes.

bool PCNT_Init_TypeDef::hyst |
Set to true to enable hysteresis. When its enabled, the PCNT will always overflow and underflow to TOP/2.

PCNT_Mode_TypeDef PCNT_Init_TypeDef::mode |
bool PCNT_Init_TypeDef::negEdge |
Polarity of incoming edge.

PCNT_PRSSel_TypeDef PCNT_Init_TypeDef::s0PRS |
Select PRS channel as input to S0IN in PCNTx_INPUT register.

bool PCNT_Init_TypeDef::s1CntDir |
Set to true to enable S1 to determine the direction of counting in OVSSINGLE or EXTCLKSINGLE modes.
When S1 is high, the count direction is given by CNTDIR, and when S1 is low, the count direction is the opposite.

PCNT_PRSSel_TypeDef PCNT_Init_TypeDef::s1PRS |
Select PRS channel as input to S1IN in PCNTx_INPUT register.

uint32_t PCNT_Init_TypeDef::top |
Initial top value (refer to reference manual for max value allowed). Only used for pcntModeOvsSingle (and possibly pcntModeDisable) modes. If using pcntModeExtSingle or pcntModeExtQuad modes, the top value is reset to HW reset value.
