LED0
FLASH-LED indicates the GSM activity status of the modules inside the Snap-in Socket on the Q26
Carrier Board and can also be used to drive an LED. Application designers have the option of
selecting to use GPIO4 for concurrent common GPIO use and FLASH-LED.
By default, R305 is connected on the Q26 Carrier Board to allow GPIO4 to be used as a regular GPIO
and LED0 at the same time.
Refer to command
