TMS320F280049: TMS320F280049 CMP6_HP3 can't trigger EPwmXbarRegs TRIP8

Dear Colleague,

Our customer are using TMS320F280049, they find if they use CMP4_HP0, when CMP4_HP0 > Cmpss4Regs.DACHVALS.bit.DACVAL, it could trigger EPwmXbarRegs TRIP8.

But if they use CMP6_HP3, when CMP6_HP3 > Cmpss6Regs.DACHVALS.bit.DACVAL, it can't trigger EPwmXbarRegs TRIP8. They have enabled trigger function. And they need use CMP6_HP3.

Below are CMP4 & CMP6 register status and code, please help us check it. 

Thanks a lot!
