Table 9. MODE[2:0]

MODE[2:0]

The three MODE[2:0] bits define eight operating modes for the IC.

Ambient Configuration Register (0x02)

Writing to the Ambient Configuration register aborts any ambient data conversion (Registers 0x04 to 0x0F) if already in

progress, applies the new settings immediately, and initiates a new conversion.

*When TEMPEN is set to 1.
