SPI Delay time

I was thinking about why my dasy chain L6470 solution didn’t work, and I came up on a question I could not answer myself.

How many µSeconds delay is there between the MOSI changing state and the Clock pin changing state? On the Scope it looks simultaneous.

I have no idea but I remember I saw this a few days ago. I have not had time to investigate.


See page 4. I am not sure if this applies to your device though. Besides, I am not sure how to apply the NOPs.

Yea, so I understand the tsetup and tvalid times. The question is, how does tinyclr clr and .netmf do it?
