On Linux® platforms, the WLAN firmware is downloaded by the SDIO driver to the WiLink 8 device while in operational mode. RTTT operational mode provides a debug connection to the IC using the dedicated RS-232 interface to the read and write registers.

To enable debug capabilities, such as writing and reading registers and firmware globals, use the RTTT operational mode.

Figure 3-3 shows the Settings area with Operational mode selected.
