HTU writing to GPIO registers

Is it possible to configure HTU to write directly to GPIO registers? Or maybe HTU - DMA - GPIO chain will work?

It will allow to drive more pins using N2HET without calling CPU ISRs

Sorry for newby questions, I'm trying to understand TMS570 architecture.

Hi Yaroslav

Yes, it is possible to write from HTU directly to the GPIO registers of NHET. The HTU-DMA-GPIO chain wouldn't make much sense as the HTU does not supply event to DMA module.

Hi,

can you post some example code, or some guidelines, or some links to achive that?

Cannot found any documentation on HTU other than TMS Tecnical Reference.

thank you,
