Resume
The Host resumes signaling, the hardware detects this as resume. The hardware enables the
oscillator and asserts the RSM interrupt.
Remote Wake-up,
Function
The hardware detects an INT0/INT1 or PD0 if enabled, and starts resume signaling upstream.
Finally, the hardware enables the oscillator and asserts the RSM and FRWUP interrupts.
