Hello TI Team,
I don't understand how to calculate the period of the waveform I am generating via ETPWM pin of the microcontroller. To be clear I understand how to set the period and duty cycle and I physically see on an oscilloscope these parameters change as the SW parameter is updated. I don't understand how the period/frequency is determined based on these parameters.
In Halcogen
Clock Configuration
TB Clock (MHz) = 110
VCLK3 (MHz)=75
PWM Configuration
Period (ns)=100,000
Duty (%)=80
Here I expected the period of the PWM waveform to be 100,000 ns. However on the oscilliscope I see the period of the PWM is approximately 1.32s. Can you describe to me how this 100,000 period value converts to the physical time period? Am I doing something wrong?
