I now use S6E2HG's CSIO SPI as master  to control LTC1867 (read 6-channel AD conversion value), CSIO's SPI supports the following timings:

None of the above can meet the requirements of LTC1867.

LTC1867 requires:

The signal mark level of serial clock output is set to LOW,and

The transmit data is output at a rising edge of serial clock

Can FM4 CSIO  SPI mode meet this requirement? Please expert for guidance.

Thanks.
