PWM_CAP0_SW When set, a software-forced capture on channel 0 is triggered. (WO)
PWM_CAP0_IN_INVERT When set, CAP0 form GPIO matrix is inverted before prescaling. (R/W)
PWM_CAP0_PRESCALE Prescaling value on the positive edge of CAP0.
PWM_CAP0_PRESCALE + 1. (R/W)
PWM_CAP0_MODE Edge of capture on channel 0 after prescaling. When bit0 is set to 1: enable
capture on the negative edge; When bit1 is set to 1: enable capture on the positive edge. (R/W)
PWM_CAP0_EN When set, capture on channel 0 is enabled. (R/W)
