Marvell Wireless Module

These are the out-of-band signals communicating with the Marvell wireless mesh networking module, which contains the Libertas family 88W8388 chip.

If the direction is listed as "output", the signal is generated by the Marvell module. If the direction is listed as "input", the signal is generated by the laptop and passed to the Marvell module.

Pin Name	Pin Number	Signal Name	Direction	Description
GPIO02	49	WAKEUP_EC	Output	Driven high to wakeup the EC when the module has been told the laptop is in suspend. This signal must not be deasserted until the module sees USB activity from the master.
?	?	WAKEUP_WLAN	Input	Driven high to inform the WLAN module that the laptop is no longer in suspend mode. What is the handshake reflecting that the module has seen this signal ?
GPIO01	50	WLAN_ENLED#	Output	Driven low to indicate that the module has associated with a mesh/AP
GPIO12	46	WLAN_ACTLED#	Output	Driven low to indicate actual packet transfers to/from the laptop (not relayed packets).
GPIO13	45	RX/BAT_L0	Input
GPIO14	44	BAT_L1	Input
GPIO15	43	BAT_L2	Input
RESETn	41	WLAN_RESET#	Input	Asserted by the driver on the host to reset the module.
GPIO00	51	N.C.	-	While connected on B2 XOs, this pin should be left unconnected.
GPIO06	?	N.C.	Input	Unclear if this has a dedicated function (or what pin it is.)
GPIO07	?	N.C.	Output	Reserved for R.F. reset (?)
