General Purpose I/O
GPIO6 / BT_STATE
GPIO7 / WL_ACTIVE
GPIO8 is not used, and should be left open.
In stacked configuration, all GPIO signals are routed from G24 to host, and are used as GPIO
signals for G24 user application.
For more details on implementing a GPIO interface for use with G24, please refer to the

Module Hardware Description
Description
I
Used only in 3-Wires coexistence.
If Bluetooth is transmitting high priority data, the
Bluetooth device shall send a 20 s pulse on this line
right after BT_PRIORITY line has been asserted.
After this pulse, BT_STATE will go LOW to indi-
cate RX Priority Bluetooth transmission or HIGH
to indicate TX Priority BT transmission.
O
In 2-Wires coexistence: When High WLAN is
transmitting or receiving packets.
In 3-Wires coexistence: When Low, Bluetooth is
allowed to transmit. When High, Bluetooth is not
allowed to transmit. If Bluetooth is already trans-
mitting packets when signal is asserted, then Blue-
tooth will shut off right after the current transaction
is completed.
