Im current using the trip zone function

why the

EPwm1Regs.TZSEL.bit.OSHT1 is set

the

EPwm1Regs.TZFLG.bit.OST is set too??

and the EPwm1Regs.TZFLG.bit.OST cannot be clear

thru EPwm1Regs.TZCLR.bit.OST=1

Hello,
Did you check your TZ1 pin? Is it low or high? Did you initially tie it high?

Best regards,
Maria

Hi, Im using concerto device
and I do the following
EALLOW;
GpioG1TripRegs.GPTRIP1SEL.bit.GPTRIP1SEL = 16; //Select PD0_GPIO16 as TZ1n
EDIS;

and make the GPIO16 tie high
GpioG1DataRegs.GPASET.bit.GPIO16 = 1; // uncomment if --> Set High initially

Oh!!! yes I solve the problem!!!

I do the following
EALLOW;
GpioG1TripRegs.GPTRIP1SEL.bit.GPTRIP1SEL = 12 ; //Select PD0_GPIO12 as TZ1n (from the pinout)
EDIS;
and
GpioG1DataRegs.GPASET.bit.GPIO12 = 1; // uncomment if --> Set High initially

this work properly thank you!!!!!
