SPI is a synchrone serial interface.

It's using a SDI /SDO line (serial Data Input and Output) and a synchrone clock SCLK.

You are able to clock in or out the data needed at high speed.

'Memory mapping' is done with the CE select line.

You can interface more than one 3110 without loosing any information on any other NOT selected device on your SPI bus.
