### detachInterrupt()

Examples |
    ...

    // attaches 'myFunction' function to SPI transfer complete interruption
    SPI.attachInterrupt(myFunction);

    ...

    void myFunction() {
      // print to serial when a transfer complete
      // interruption is generated
      Serial.println("SPI transfer complete...");
    }

    ...

    // stops the SPI transfer complete interrupt generation
    // and detaches 'myFunction' function.
    SPI.detachInterrupt();

Description | The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard named by Motorola that operates in full duplex mode. Devices communicate in a master/slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select (chip select) lines using a pin for each device. The detach() method deactivate the SPI interrupt and detaches the interruption function. On Wiring v1 boards the SPI pins are: SS=24, MOSI=25, MISO=26 and SCK=27. On Wiring S board the SPI pins are: SS=20, MOSI=21, MISO=22 and SCK=23.
