t9 3

SCLK falling edge to SDO valid

t10 3

CS rising edge to SDO tristate

t11 3

CS falling edge to SDO valid (for readback MSB only)

1 Guaranteed by design and characterization. Not production tested.

2 All input signals are specified with rise time (tR) = fall time (tF) = 5 ns (10% to 90% of VDDIO) and timed from a voltage level of 1.2 V.
