W_​Disable1# (GPIO)

O

Used for Wi-Fi* RF-Kill control.

This pin can be connected to a platform switch or to processor GPIOs (recommendation- if possible do not use GPIOs that have Platform impact as “bootstraps” during platform init).

The signal must keep value in Sx state (configured in BIOS)

Note:Signal name not available in processor ballmap. This is a representation of GPIO used as CNVi signal.
