In our application we are reinitializing ADF7020-1 configurations for every 10 sec.
In our observation even respective master is OFF , Interrupt is generated by adf7020-1 for every 10sec.
If Master is ON then interrupt is generated by ADF7020-1 in less than 10 sec.what is the reason behind this observation?
Even if the master is off, the ADF7020-1 will continue operating as configured, as long as power is still applied to it. So, it will remain in the Rx state and will continuously receive data until instructed to go to another state.
The INT/LOCK pin is asserted upon detection of the sync word, and is automatically deasserted again after nine data clock cycles.
