RM46L852 ETPWM stop when halting the target

Hi all, I have two questions.

Is there a way to prevent ETPWM output to stop at emulation halt ?

Is it possible to control polarity of ETPWM pin output when ETPWM clock (VCLK4) is halted?

Vasco, try FREE_SOFT...

Vasco,

The CPU's entry into emulation mode (halt) also causes a trip-zone input (nTZ6) to be asserted to the ePWMx modules. You can configure the ePWMx module response to this trip-zone input to the way you want.

There is no way to detect VCLK4 being shut off inside the ePWMx modules. The PWM outputs will be "frozen" in this case.

Regards,
Sunil

Hello Anthony and Sunil,

thank you, all is clear now.

So i can change FREE_SOFT to get etpwm clock running during emulation halt and using TZSEL / TZCTL i can define the behavior of etpwm pins at emulation event .
