analog GPIO level, respectively. Use the manual AGPIO level toggle to control the external RF components, like to power up/down the PA, and
so on.
Auxiliary DAC Output
The auxiliary DAC can supply bias voltages, analog control voltages, or other system functionality. See the
Temperature Sensor section for the details. Analog GPIO 0 through 3 provide the alternative function for the Aux DAC 0 through 3 output,
respectively.

INTERRUPT

The ADRV9001 features the general-purpose interrupt output pin (GP_INT). The GP_INT pin can alert the baseband processor that an
important event or error regarding the device operation occurred. These events include PLL locking, stream processor errors, ARM exceptions,
and so on.
Table 100 describes the interrupt sources and their bit positions. An Interrupt source can be masked so it is not transmitted to the BBIC on the
GP_INT pin or in status registers. An interrupt is masked when the corresponding mask bit is set to '1'. The GP_INT pin represents a logical OR
of the enabled GP_INT mask sources. It is not necessary to enable all the interrupt sources.

There is full control (through public API functions) to set/get the mask, sticky mask, and status registers (although the status register is
read-only). Hence, tailor solutions (recovery actions) to handle the different events/interrupts.
Use adi_adrv9001_gpio_GpIntMask_Set() to mask the corresponding interrupt events after device initialization. When a rising edge is
detected on the GP_INT pin, the baseband processor should call the API command adi_adrv9001_gpio_GpIntStatus_Get() to find out which
interrupt sources trigger the interrupt signal.
