Global Resume
The Host resumes signaling, the hardware detects this as global resume and propagates this
signaling to all downstream ports. Finally, the hardware enables the oscillator and asserts the
RSM interrupt.
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.
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.
