With an spi connection there is always one master device (usually a microcontroller) which controls the peripheral devices. If you want to communicate between for example an arduino uno and a you also find the used pins in the pinout overview table in the special articles for the arduino uno and arduino mega. Spi.attachinterrupt(handler) − function to be called when a slave device receives data from the master.
