SYNCHRONIZATION AND GENERAL-PURPOSE I/O
GPIO09I/O, PDGeneral-Purpose Input/Output pins. The pins can be used to control and respond to various commands. They may be configured to be input signals for the corresponding GPIOs on the serializer or they may be configured to be outputs to follow local register settings. At power up, the GPIO pins are disabled and by default include a pulldown resistor (25-kΩ typ).
See Section 7.4.11. for programmability. If unused, leave the pin as No Connect.

CONFIGURATION AND CONTROL
IDX46SI2C 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 7-17.
MODE45SMode Select configuration pin.
Connect to external pullup to VDD18 and a pulldown to GND to create a voltage divider. See Table 7-1.
PDB3I, PDInverted 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 will power down the device and consume minimum power. The default function of this pin is PDB = LOW; POWER DOWN with an internal 50-kΩ internal pulldown enabled. PDB must remain low until after power supplies are applied and reach minimum required levels. See Section 8.4.1.
INPUT IS 3.3-V TOLERANT
PDB = 1.8 V, device is enabled (normal operation)
PDB = 0 V, device is powered down.
