WLAN self tests

Context
The sequence of events during the start-up of WLAN is:
1 PMEN is asserted high when the WLAN module is first enabled by the Host.
2 WLAN module should respond by driving CLK REQ high to request the 38.4MHz clock.
3 Host engine turns on the 38.4MHz clock and then generates the SPI Clock to start the download of software
to the WLAN module.
The steps for running the WLAN self tests with Phoenix are listed below.
Steps
1. Set the phone into Local Mode .
2. From the File menu, select Scan Product and check that the correct product version is displayed.
3. From the Testing menu, select Self Tests. This opens up a Self Test dialogue box, as shown below.
Select the ST_WLAN_TEST check box as shown and then click on the Start button. The test turns on the
WLAN, sets up the SPI interface and then downloads the WLAN firmware into the WLAN module. During
the download the WLAN acknowledges the data blocks and so the self test is a good way to confirm that
the WLAN module is communicating with the Host. The result column will change to Passed after a few
seconds if operating properly.
