Hi Wenzhuo,

I'm a little unclear as to the last paragraph of this message. Does the
app configure the callback to handle the reset, or does the driver set
up a callback automatically and handle the event itself? [In other words,
who/what is the "handler" in the final sentence, the driver or the app?]

Thanks,
