SPI Mode, can someone confirm this is Pol=0 Pha=1?

Attached.

I'm like 99% sure it's clock polarity is 0 (low to high) and the Phase is 1 where data is changed at rising edge and sampled at falling edge.

But... I'm getting fairly difficult to rationalize data when using this mode, and equally difficult when using 0/0. So I just wanted to check with some experts before I smash my face on my desk.

This is my first time dealing with SPI on STM32, so I'm just ruling out fairly simple errors I might be making. I hooked up a scope and the waveforms I'm getting are correct and looks really solid. I'm just not sure about the sampling.

Thanks

Clock idles low and data is changed on the leading edge of the clock pulse and sampled on the trailing edge.  Whatever phase/polarity settings give you that behavior is what you want.

Looks like you need clock polarity 0 and phase 1.

What device are you trying to communicate with?

Yea, I was 99% sure. Just confirming. It's a Motorola SBC, and it's starting to be a pita.
