Other Parts Discussed in Thread: AM3359
hello
every expecter
This is Tomiyama from Tokyo.
I want to use am3359 as a device,but I could not set active IRQ of usb0.
I could not recive IRQ from PC. And active IRQ alway UART2.
Which register should I set up?
These are I setup routine.
best regards
tomiyama
