Besides the main host interface signals, a couple of other pins also complement the host interface. See AN1219 for more details:
• The GPIO/WUP pin should be used by the host to wake up the WFM200S when in power-save mode. This pin is programmable and
if power save is not enabled on the device, this pin can be configured as a GPIO. Note that this pin should be LOW to enable the
WFM200S to reach sleep or shutdown modes.
• GPIO/WIRQ can also optionally be used as a duplication of the IRQ signal from SPI or SDIO. If this is not required, the pin can be
configured as a GPIO.
