TMS320F28377S: EPWM TZ1 & TZ2 interrupts are generated at the startup while the conditions are false.

Part Number: TMS320F28377S
Other Parts Discussed in Thread: SYSCONFIG, C2000WARE

I am using code composer studio version 12, Sysconfig 1.17.0, C2000Ware 5.1.0 for my project. I have setup hardware trips for my two EPWMs using TZ1 and TZ2 that are assigned using GPIO61 and GPIO62 through input X-bar. Entire EPWM settings including the trip zone and the trip interrupt are done using the SysConfig tool. The settings for one of the EPWM are as shown below:

The problem is that the the trip zone interrupt is called just at the system power up although the TZ pins are maintained at logic high level. Please guide about this so that there is no false trigger at the system powerup.
