General Purpose I/O

W24 incorporates 8 General Purpose I/O interface. The interface consists of the following pins
(see

Table 2-14

):

In Stand alone configuration, GPIO pins 1 to 3 act as general purpose inputs.

GPIO pins 4 to 7 function as Bluetooth coexistence control/indicators for the W24 to use with a
Bluetooth interface in order to avoid RF collision between Bluetooth and Wi-Fi transmission.
There are 2, 3 or 4-wires coexistence configurations possible. Below is the functionality

GPIO4 / BT_PRIORITY

I

In 2-Wires coexistence: When High, BT is trans-
mitting or receiving high priority packets.
In 3-Wires coexistence: When High, BT PA is on or
BT is receiving data.

GPIO5 / BT_FREQ

I

This pin is not used for 2-wire and 3-wire Bluetooth
coexistence scheme. This pin can be used for
4-wire interface if needed.
This pin should either be left floating or be con-
nected to ground.
