SPI - CPHA CPOL

Post by Jay Dee »

Hi,
I always get myself confused on this one, could someone with more knowledge let me know if I have got this correct!
FC SPI Settings for Motorola definitions

Clock Polarity
CPOL = 0 FC = Idle Low
CPOL = 1 FC = Idle High

Clock Phase
CPHA = 0 FC = Leading Edge
CPHA = 1 FC = Falling Edge

Sample Point
Middle ??
End ??

Thanks, J.
