These are the out-of-band signals communicating with the Marvell wireless mesh networking 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 (?) |
