AT43USB325
8.5.4.3
Remote Wake-up, Downstream Ports
The hardware detects a connect/disconnect/port resume and propagates resume signaling
upstream. Finally, the hardware enables the oscillator and asserts the RSM interrupt.
8.5.4.4
Remote Wake-up, Embedded Function
The hardware detects an INT0/INT1 and propagates resume signaling upstream. Finally, the
hardware enables the oscillator and asserts the RSM and FRWUP interrupts.
