Host asserts nSTROBE low to indicate valid data.
3.
Peripheral acknowledges host by setting BUSY high.
4.
Host sets nSTROBE high. This is the edge that should be used to clock the data into the Peripheral.
5.
Peripheral sets BUSY low to indicate that it is ready for the next byte.
6.
The cycle repeats, but this time it is a command cycle because nAUTOFD is low.
