5.3 LED mode behavior
State Definition Interpretation
OFF The LED is emitting no
light.
Radio is incapable of transmitting.
This state is indicated when the card is not powered, the
W_Disable# signal is asserted to disable the radio, or when the
radio is disabled by software.
ON The LED is emitting
light.
Radio is capable of transmitting.
The LED should remain ON even if the radio is bit actually
transmitting. For example, the LED remains ON during
temporary radio disablements performed by the Mini Card of its
own volition to do scanning, switching radios/bands, power-
management, etc.
If the card is in a state wherein it is possible that radio can begin
transmitting without the system user performing any action, this
LED should remain ON.
