If CS is returned high before all data bits are output, the SDATA and SCLK outputs will complete the current data bit and then go to high impedance. 19. If CS is activated asynchronously to DRDY, CS will not be recognized if it occurs when DRDY is high for 4 clock cycles. The propagation delay time may be as great as 4 CLKIN cycles plus 160 ns. To guarantee proper clocking of SDATA when using asychronous CS, SCLK(i) should not be taken high sooner than 4 CLKIN cycles plus 160ns after CS goes low. 20. SDATA transitions on the falling edge of SCLK(i).
