In S3, data is made available by the external device on the falling edge of CLKOUT and is sampled
on the rising edge of CLKOUT with TA asserted.
In S4, the external device can stop driving data after the rising edge of CLKOUT. However data
could be driven up to S5.
For a read cycle, the external device stops driving data between S4 and S5.
