| 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, counter value is reset to HW reset value.

| PCNT_Mode_TypeDef PCNT_Init_TypeDef::mode |
| bool PCNT_Init_TypeDef::negEdge |
Polarity of incoming edge.
- pcntModeExtSingle mode - if false, positive edges are counted, otherwise negative edges.
- pcntModeExtQuad mode - if true, counting direction is inverted.

| 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.
