Hi all,
I have basic doubt in USB host controller. On what
basis the host will send IN and OUT tokens? Assume the device has some data
and wants to send to host. One way is during status read, the device
can reply with interrupt status (if it is configured for interrupt mode). How to
indicate the host, if it is not in this mode?
Waiting for reply.
Thanks and
regards,
