3.4.2 WAKE# Signal

WAKE# pin (the signal that the module uses to wake up the PC) supports software
control.
This signal is used for module to wake up the host. It is designed as an OC (Open
Collector) gate, so it should be pulled up by the host and it is active-low.
When the module wakes up the host, the WAKE# pin will output low-level voltage.
