TMS320F2800137: F2800137 Global load of AQCTLA

Tool/software:

Hi,

I am using ePWM1 and ePWM2. ePWM2 is linked with ePWM1 for period and for Global PWM Load link. All registers are using shadow registers and are loaded normally at counter 0 right after setting ePWM1.GLDCTL2.OSHTLD.

It seems that for AQCTLA register, it seems that AQCTLA is loaded at 0 regardless of even if ePWM1.GLDCTL2.OSHTLD was not set yet (all registers not fully updated yet) causing some PWM issue. (shoot through).

Is that a problem or I am missing something in the configuration? Sysconfig is also not setting shadow load mode in AQCTL for AQCTLA even if check in sysconfig. Anyway, I updated AQCTL manually. 

I also need

Thanks,
