  • Page 45: Host Wake-Up Signal Handling

    3.2.3. Host Wake-Up Signal Handling We name the pin number 23 of WizFi210 as “Host wake-up signal”. Host wake-up signal is ACTIVE HIGH signal. Host processor must give the SPI clock and SPI read operation, as long as host wake-up signal is HIGH.

  • Page 46: Spi Interface Parameters

    One dedicated GPIO signal known as host wake-up is available for data ready indication from Slave WizFi210 to Master Host processor. Master host processor must provide clock as long as host wake-up signal is active. Host processor can make use of GPIO interrupt (edge triggered low-to-high transition) to receive the data from WizFi210.
