12.3.5

Duty cycle registers (PWMDCRx)

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.

Capture Sensitivity

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

3:2

CIE[2:1]

Capture Interrupt Enable

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

1:0

CF[2:1]

Capture Flag

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.
