7.3.10.2 STANDBY Pin

The STANDBY pin is active low. The device is in a low current mode on the PVDD and VBAT pins while the output pins are placed into a Hi-Z state. All internal analog biases disabled. In STANDBY and while DVDD is present, the I2C bus is active and the internal registers are active.

Internally this pin is connected to DVSS with a 100 kΩ pull-down resistor.

By default, the pin is configured in three level standby mode (TLSBY).

It is possible to communicate via I2C while STANDBY pin is low and the STANDBY pin functionality can be set to two level mode by updating the TLSBY value of Micellaneous Control Register 4 during power up sequence.
