Host Interface Timing Diagram 8.1 SDIO Pin Description The module supports SDR12(25MHz) and SDR25(50MHz, dual rates) in addition to the 1.8V default speed(25MHz) and high speed (50 MHz). It has the ability to stop the SDIO clock and map the interrupt signal into a GPIO pin. This ‘out-of-band’ interrupt signal notifies the host when the WLAN device wants to turn on the SDIO interface. The ability to force the control of the gated clocks from within the WLAN chip is also provided.
