11.2.2 Definitions
• Transmitter: the device that sends the data to the bus
• Receiver: the device that receives the data from the bus
• Master: the device that initiates and terminates a transfer and generates clock signals
• Slave: the device addressed by a master
• Multi-master: more than one master can attempt to control the bus at the same time
without corrupting the message
• Arbitration: procedure to ensure that if more than one master simultaneously tries to
control the bus, only one is allowed to do so and the message is not corrupted
• Synchronization: procedure to synchronize the clock signals of two or more devices
