Hi team,

For ADC128S102, which SPI mode need to be used? Mode 1, 2, 3 or 4?

    Hi Py,

    Using CPOL = 1, CHPA = 1 should suit the ADC128S102.  This would typically be SPI mode 3 and most processors refer to SPI in modes 0, 1, 2 or 3.  The SCLK dwells high with valid data to DIN and from DOUT valid on the rising SCLK edge.
