CALPWRON and HRMSTEP for TMS320F28377D

Other Parts Discussed in Thread: TMS320F28377D, TMS320F28379D

Hi All,

I'm configuring the PWMs for EPWM1, EPWM3 and EPWM5 on a TMS320F28377D.

Now after enabling HResolution and connecting the PWM modules by CMPALINK I try to set HRMSTEP with value 55d for all 3. but I can only write to PWM1, the others ignore writes (stay zero). I also can't enable CALPWRON on the 3th and 5th module.

Is this how it's suppose to be or...?

Best Regards,

Tjarco Boerkoel
