WebGPIO alternate functions. GPIO alternate functions are used to support two sets of Arduino shield expansion peripherals. The 52-pin expansion port (EXP port) is driven from GPIO0-3. For each pin, the relevant bit of ALTFUNC must be set to use the alternate function. If this bit is not set to use the alternate function, the pin is used for GPIO.
