Hi,
We are generating phase shifted PWM signals from F28377D for cascaded multilevel converter. The carrier frequency is around 450 Hz. only. We are loading the counter compare registers on either CTR = Zero or CTR = PRD ( CMPCTL.LOADBMODE = 10) from shadow register. Therefore, the sampling for 50 Hz modulating signal is only 36 (450/50*4) . If we use immediate mode, the results become very noisy and the output is nowhere to the sinusoidal.
Is there any way to upload the counter-compare register from shadow register in much faster rate? Is it possible to upload counter-compare register for external event?
