I found there  is same min & Max timing limit value of td(SCLK-D1) , it seems can’t make sense.

    One more concern for McSPI timing parameter: why separated SM6 but with the same MIN/MAX value?

    Hello,

    The first table is a typo.  Min = -1-P, Max = 1-P.

    The 2nd table is correct.  At one point the values may have been different but the end result is that they are the same.

    Regards,

    Kyle

    Hi Kyle

    About Q9 td(SCLK-D1) in MODE 0 READ Sequence, the actually test result is similia with Q4 td(CS-SCLK) which can't meet the spec Min : -23.2ns , Max -21.2 ns. (P =22.2ns)

    According the timing diagram , Q9 seems same with Q4, can you help double confirm my test result whether is fail from your view?
