 Connect the application’s MISO line to port F1 of the WLN to receive data from the

Slave.

 Connect the application’s SCK line to port F4 of the WLN to send the Master’s serial

clock.

 Connect the application’s /SS line to port F5 of the WLN to select the WLN Module.

 Connection the application’s INT line to port G0 of the WLN to receive interrupts from the

Slave. This indicates that data is available on the WLN.

Caution

If the Module is connected to a circuit that is powered on while the Module is

powered off, the design should ensure that no logic highs are present on the

connections while the Module is powered off. Otherwise, the Module can be

damaged beyond repair. If the state of the connections cannot be controlled,

insert a tri-state buffer between the Module and its Host. For additional

information, see Appendix B, Power Control.

Caution

The 3.3 V power supply should be a low-noise design, with less than

150 mV ripple at the maximum average transmit current. The power supply

should also be designed to provide sufficient power to handle the Module’s

power-up inrush current. For additional information, see Appendix B, Power

Control.
