Hi Team,

I just noticed a discrepancy in following figures in TRM for TMS320F28069: (Fig 3-3| Fig 3-5) & Fig 4-4

FIG 3-3

Fig 3-5

Fig 4-4

If you carefully have a look at the above figures, DCxEVT1.sync signal is what I want to highlight. In Fig 4-4 DCxEVT1.sync signal seems to be ORed and fed to the mux block for generating EPWMxSYNCO while the other two figures don't. The later is what I observed to be true on the hardware.

Let me know if I'm wrong in interpreting the figures.

Regards,

Gautam

Gautam,
Figures 3-3 and 3-5 are correct, these were updated a while back. Note: We will be propagating those documentation changes to F2802x, F2803x, and F2805x.

It seem that Figure 4-4 must have been overlooked as it was part of the HRPWM section. I will submit a bug for this to be corrected.

Thanks,
Cody
