LAUNCHXL-F2800137: Epwm

Hi Manoj,

The trip zone module overrides the output of the dead-band module(which is responsible for creating complementary function). You can use the trip-zone module to drive both outputs to a specified state when the trip condition is true(either as a one-shot trip or a cyce-by-cycle trip). We have examples in C2000Ware demonstrating usage of the trip-zone module.

Thank you,

Luke

Hi Manoj,

The source for the tripzone in example 1 is GPIO12. This is shown above the main function in the comments:

Are you trying to use a software trip? This is controlled through the TZFRC register.

Thank you,

Luke

Hi Manoj,

The software one-shot trip is cleared through the TZCLR register. The driverlib functions to control TZCLR and TZFRC can be found in the register to driverlib mapping tables at the end of the EPWM chapter, or in C2000Ware/driverlib/f280013x/driverlib/epwm.h in your C2000Ware installation.
