TMS320F280049: HRPWM support down count mode?

Shaoxing Ke

Part Number: TMS320F280049

Hi Experts,

I am asking for my customer here.

From TRM, the High-resolution period is not compatible with down-count mode, so down-count mode not support the High-resolution period. But down-count mode support high resolution duty and Phase? Right? Thanks.

Hi Shaoxing.

This excerpt is correct, down-count mode is not supported in HRPWM mode.

High resolution phase implies high resolution period is being used, so this is not available. However I don't believe we have any restrictions on using high resolution duty, even if down-count mode is being used.

Thank you,

Luke

Hi Luke,

So the down-count mode only support high resolution duty, and others Up-Down and Up count mode support all! Right? Thanks.
