CONFIGURATION AND CONTROL
IDX 46 S I2C Serial Control Bus Device ID Address Select configuration pin.
Connect to an external pullup to VDD18 and a pulldown to GND to create a voltage divider. See Table 5-13.

PDB 3 I, PD Inverted Power-Down input pin. Typically connected to a processor GPIO with a pulldown. When PDB input is brought HIGH, the device is enabled and internal registers and state machines are reset to default values. Asserting PDB signal low powers down the device and consumes minimum power. The default function of this pin is PDB = LOW; POWER DOWN with an internal 50kΩ internal pulldown enabled. PDB must remain low until after power supplies are applied and reach minimum required levels. See Section 6.4.1.
INPUT IS 3.3V TOLERANT
PDB = 1.8V or 3.3V, device is enabled (normal operation)
PDB = 0V, device is powered down.
