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

NOTE A:
– – – – 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. Parts with date code earlier than 13XXXXX have these discrepancies:
(Date code is a 7 digit code next to the TI where the first digit indicates the year and the second digit is the month of production. 13,
in this case, is 2001 and the month of March.)
FS is not ignored even if the device is in microcontroller mode (CS triggered).
FS must be tied to DVDD.
