EXAMPLE:
The following C program shows the use of the PWMART functions.
Program description:
This program detects the event (rising edge) at ARTIC1 pin and generates the PWM signal of
frequency 50KHz with duty cycle 33% on the PWM1 pin for ST72F521 device with a 4MHz ex-
ternal clock. The output compare signal is obtained on the PWM2 pin.
