3.5 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 gate, so it
should be pulled up by the host and it is active-low.
When the module wakes up the host, the BB Chip hold 1s high-level-voltage pulse
and then module output low-level-voltage to wake the host.
