When does SPI Master STARTED event occur?

Hi Simon,

Indeed, that is correct.

I got the full SPIM transaction working using PPI by following the "Figure 71: SPI master transaction" diagram. CS needs to go active low before the START task anyways. So STARTED is not used at all in this case.

1 cycle between START and STARTED? Good to know.

Thanks,
Max

Hi Max

I don't think what you're describing is feasible, as there won't be enough time to do this by using the STARTED event. I'd rather suggest using a short timer to hold the timing instead, as there's only one cycle of the PPI (62.5ns I believe) from the START task until the STARTED event occurs.

Best regards,

Simon
