Hi, Scarlett,

It looks like their s/w has a button for default. I would suggest they use that as our device was designed to be compatible with the SPI standard.

Best regards,

Don

Hi Morita-san,

I'd like to confirm with you that the last picture where you marked >2us should be <2us instead, right?

Thanks

Scarlett

Scarlett,

No, >2us is correct. Min has to be 2us before next transaction, but it can be greater than.

Hi Scarlet,

Unfortunately DRV8889-Q1 datasheet does not have such a timing chart. Please refer DRV8912-Q1 instead. SPI timing chart is same.
