Scope of work
A pulse width modulated (PWM) signal with fixed frequency and a
defined duty cycle is generated using GPT12.
The timer T3 of GPT1 is used in timer mode with its count direction
configured to “down-counting”. On underflow of timer T3, the Output Toggle
Latch (T3OTL) is toggled and the value of timer T2 or T4 is transferred into
timer T3 depending on T3OTL value. The state of an LED is toggled in an
interrupt service routine which is triggered by the timer T3.
