1 Guaranteed by design; not production tested.

2 The MSB presents an exception to this parameter. The MSB clocks out on the falling edge of CS. The remaining DOUT bits are clocked after the falling edge of SCLK

and are governed by this specification.

3 This parameter may need to be expanded to allow for proper capture of the LSB. After CS goes high, the DOUT line enters a high impedance state.
