How to eliminate the One-Shot pulse from the MCPWM modul with carrier modulation

[rob_bits]

Hello,

I would like to implement the example waveform from the technical reference manual in the MCPWM section, PWM Carrier Submodule, where the generated signal does not have One-Shot pulse in the beginning (Figure 120: Example of Waveforms Showing PWM Carrier Action).

I was able to generate the signal which has a different first pulse as the subsequent pulses (Figure 121: Example of the First Pulse and the Subsequent Sustaining Pulses of the PWM Carrier Submodule) however I cannot disable the first pulse.

The documentation says:
The width of the first pulse is configurable. It may assume one of 16 possible values and is described by the
formula below:
T1stpulse = TPWM_clk ×8×(PWM_CARRIERx_PRESCALE +1)×(PWM_CARRIERx_OSHTW T H +1)

So if I set PWM_CARRIERx_OSHTWTH to 0, still the pulse width will be equal to the period of the subsequent pulses.

Do I need to implement a dead time configuration, or how can I eliminate the unnecessary one pulse signal?

Regards,

Robert
