I would like to make sure the SPI signal timing between Host and PN5180. What I want to know is how NSS and BUSY should be handled.

Especially, how to control NSS and watch BUSY in read (GET) mode. Please find the attached for my understanding and tell me it is correct or not?

I appreciate your help very urgently...


Best regards,
