Auxiliary DAC Output
Auxiliary DAC can supply bias voltages, analog control voltages, or other system functionality, refer the Auxiliary Converters and
Temperature Sensor section for the detail. 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 has occurred. These events include of unlocking of PLLs, Stream Processors
errors or ARM exception, and so on.
A description of the interrupt sources and their bit positions is provided in Table 88. An Interrupt source can be masked so that it won’t
be transmitted to the BBIC on 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 of the interrupt sources.

Full control (via public API functions) is given to the user to set/get mask, sticky mask and status registers (although the status register is
a read only). Hence the user can custom tailor solutions (recovery actions) to handle the different events/interrupts.
adi_adrv9001_gpio_GpIntMask_Set() can be used 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.
