SPECIAL FUNCTION MODE
If the mode bits are 00, then the special function mode is selected, as shown in Table 15. 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 16. Table 17 shows the addresses for data readback.

Action
NOP.
Write control register.
F4 = overtemperature indicator (read-only bit). This bit should be 0 when
writing to the control register.
F3 = reserved. This bit should be 0 when writing to the control register.
F2 = 1: Select Register X1B for input.
F2 = 0: Select Register X1A for input.
F1 = 1: Enable thermal shutdown mode.
F1 = 0: Disable thermal shutdown mode.
F0 = 1: Software power-down.
F0 = 0: Software power-up.
Write data in F13 to F0 to OFS0 register.
Write data in F13 to F0 to OFS1 register.
Select register for readback.
Write data in F7 to F0 to A/B Select Register 0.
Write data in F7 to F0 to A/B Select Register 1.
Write data in F7 to F0 to A/B Select Register 2.
Write data in F7 to F0 to A/B Select Register 3.
Block write to A/B select registers.
F7 to F0 = 0: Write all 0s (all channels use the X2A register).
F7 to F0 = 1: Write all 1s (all channels use the X2B register).
