GENERAL-PURPOSE INPUT/OUTPUT AND INTERRUPT CONFIGURATION
ADRV9001 provides user with number of software configurable General-Purpose Input/Output (GPIO) pins. By utilizing API functions,
user can configure GPIO pins to operate with a variety of control or monitoring functions. ADRV9001 has two types of GPIO:
• 16 digital GPIO pins
• referenced to VIOCTRL_1P8 supply
• designated DGPIO_0 through DGPIO_15
• 12 analog GPIO pins
• referenced to VAGPIO_1P8 supply
• designated AGPIO_0 through AGPIO_11
The Digital and Analog GPIO pins can be used as real-time status signals that provide device status information from ADRV9001 to the
baseband processor when the GPIO pins are configured as outputs, with respect to ADRV9001. When set as inputs, the GPIO pins can be
used as real-time control signals that can alter the device state. The API functions related to GPIO configuration give the user the ability
to configure pins as inputs or outputs and assign functionality to specific pins.
Figure 207, Figure 208 illustrates the different functionalities that can be enabled in the device and then controlled using the Digital GPIO
pins and Analog GPIO pins, not all functionalities can be enabled at the same time.

Figure 207. Digital GPIO Features Overview
Figure 208. Analog GPIO Feature Overview
In configuring the GPIO, the two major factors to consider are the GPIO output enable control and the GPIO source control.
The output enable determines the direction of the pin, if a pin is set as output, then the GPIO I/O buffer is configured as an output.
The GPIO source control determines the functionality of the pin. The Digital GPIO source control is assigned in groups of 2, this means
that DGPIO_0 to DGPIO_1 share a single source control, DGPIO_2 to DGPIO_3 share a single source control, and so on The Analog
