Multi-master
Description
The device that sends the data to the bus.
The device that receives the data from the bus.
The device which initiates the transfer, generates the clock, and terminates the transfer.
The device addressed by a master.
More than one master device in a system. These masters can attempt to control the bus
at the same time without corrupting the message.
Procedure that ensures that only one of the master devices will control the bus. This
ensures that the transfer data does not get corrupted.
Procedure where the clock signals of two or more devices are synchronized.

Addressing I

C Devices
There are two address formats. The simplest is the
7-bit address format with a R/W bit (Figure 7-4). The
address is the most significant seven bits of the byte.
For example when loading the I
least significant bit is a “don’t care”. The more complex
is the 10-bit address with a R/W bit (Figure 7-5). For
10-bit address format, two bytes must be transmitted
with the first five bits specifying this to be a 10-bit
address.
