This example shows how to use the PWM peripheral to run capture mode.
The PWM channel 0 frequency is set to SystemCoreClock(Hz), the Prescaler is 2 so the PWM0 counter clock is 10 MHz. SystemCoreClock is set to 20 MHz.
The PWM channel 0 is configured in Timer Mode and duty cycle is 50 %. Timer/Counter is up-count mode and periodic mode. Capture mode is rising edge detection. 1 interrupts out of 3 interrupts are enabled: capture interupt(match and overflow interrupt is excepted).
The Timer/Counter runs periodically and if capture signal(PC_00) is received, the Timer/Counter value is saved at capture register and capture interrupt is occurred. In capture interrupt handler, RED LED(PC_08) is toggled.
