PN5180 'Busy' handling

I have a question about BUSY signal of PN5180.

By my understanding,

---When the host send the command to PN5180, PN5180 set BUSY to high level, And after the internal processing of PN5180 has finished, it goes low.


My question is how long this 'high' state continues. As my system watches BUSY line for waiting response data, I must set the timeout value.

I appreciate your reply as soon as possible.


Best regards,
