  • Page 16: Cyw20706 Interfaces

    7 CYW20706 Interfaces The package CYW20706 is available in may have fewer GPIOs than the die. Some of these GPIOs are fixed function IOs while others are reconfigurable for different interfaces. To accommodate its various applications, interface selection is accomplished through a combination of signal routing to CYW20706 and programming using the WICED API described in later sections.

  • Page 17: Selectable Interfaces

    6BCYW20706 Interfaces Selectable Interfaces CYW20706 supports several other interfaces besides those identified in Fixed Interfaces. Although CYW20706 supports several other interfaces, it cannot support all of its interfaces in a single hardware board design. Therefore, board designers must select which interfaces to use in a given design. The key limitation on the selectable interfaces is the number of available digital I/O pins.

    8 GPIO Information 8.1 GPIO_Pxx The Cypress WICED Studio API provides configuration support for up to 40 multiplexed GPIOs (represented as WICED_GPIO_P0 through WICED_GPIO_P39). CYW20706 uses 23 of these multiplexed GPIOs. The assignment of the multiplexed GPIOs to physical device pins is restricted from certain digital I/O pins when certain interfaces or signal functional are used.
