SPECIAL FUNCTION MODE
If the mode bits are 00, the special function mode is selected, as shown in Table 16. Bit I21 to Bit I16 of the serial data-word select the special
function, and the remaining bits are data required for execution of the special function, for example, the channel address for data readback.
The codes for the special functions are shown in Table 17. Table 18 shows the addresses for data readback.
