Duty cycle registers (PWMDCRx)
Table 52.
A PWMDCRx register is associated with the OCRx register of each PWM channel to
determine the second edge location of the PWM signal (the first edge location is common to
all channels and given by the ARTARR register). These PWMDCR registers allow the duty
cycle to be set independently for each PWM channel.
Input capture control / status register (ARTICCSR)

These bits are set and cleared by software.
These bits are set and cleared by software. They determine the trigger event
polarity on the corresponding input capture channel.
0: Falling edge triggers capture on channel x
1: Rising edge triggers capture on channel x
These bits are set and cleared by software. They enable or disable the Input
capture channel interrupts independently.
0: Input capture channel x interrupt disabled
1: Input capture channel x interrupt enabled
These bits are set by hardware and cleared by software reading the
corresponding ARTICRx register. Each CFx bit indicates that an input capture x
has occurred.
0: No input capture on channel x
1: An input capture has occurred on channel x.
