Implementation
Playing song
The song is played by repeatedly calling the function playTone() for each note, which contains
the following steps:
1. Set the PWM frequency (in Hz) through the iLLD function
IfxGtm_Tom_Timer_setFrequency()
2. Set the volume level by calling the function setVolume(). This is done by setting the PWM
duty cycle with the function IfxGtm_Tom_Timer_setTrigger()
3. Start the timer with the iLLD function IfxGtm_Tom_Timer_run()
4. Wait until the end of the note through the service function waitTime()
5. Stop the timer with the iLLD function IfxGtm_Tom_Timer_stop()
