<Supplement>
The CTCKO will be output starting with the high level then the CTDATO will be output synchronized with the
falling edge of the CTCKO clock.
The host controller should latch the CTDATO data at the rising edge of the CTCKO clock.
* The relationship between the signals in figure 8-2 and the pins is shown below.
