Command = Configure write for mode 01, FIFO threshold = 1/2
Command = Read FIFO, 1st FIFO read
§ Command = Select ch2.
Minimum CS low time for select cycle is 6 SCLKs. The same amount of time is required between FS low to CSTART for proper channel decoding.
The low time of CSTART, not overlapped with CS low time, is the valid sampling time for the select cycle (see Figure 18).
