NOTE 12: For normal short sampling, td(4) is the delay time from the falling edge of 16th SCLK to CS rising edge.
For normal long sampling, td(4) is the delay time from the falling edge of 48th SCLK to CS rising edge.

The dotted line means signal may or may not exist, depending on application. It must be ignored.
Normal sampling mode, CS initiates the conversion, FS must be tied to high. When CS is high, SDO is in Hi-Z, all inputs (FS, SCLK,
SDI) are inactive and are ignored.
