8.1 SDIO Pin Description
The module supports SDIO version 3.0 for all 1.8V 4-bit UHSI speeds: SDR50(100
Mbps),SDR104(208MHz) and DDR50(50MHz, dual rates) in addition to the 3.3V 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.
