DRV8873: SPI Communication Mode

Part Number: DRV8873

Hi all,

One of my clients asked the following about DRV8873:

"It is not explicitly called out in the spec sheet, but do you know which of the four modes TI requires to communicate?

Clock Polarity (CPOL) and Clock Phase (CPHA) are critical to get the correct timing.

It appears that Mode 0x2 is correct. If you could confirm."

 

Thanks for your time!
