Our customer will use AD7357.

Its serilal interface timing describes datasheet rev.B P.18 Figure 30 .

Figure 30 says that first SLCK edge after CS_ low is falling edge.

Could you teach me if there is any problem  when the first SCLK edge  after CS is rising edge ?

The customer would like to continues to input SCLK without stopping when CS is high because his deisgn's limitation .

 In that case ,the   first SCLK edge after CS_low may be rising edge.


Please let me know your advice .
