of the I
issues in some systems.
The I
corruption if two or more masters attempt to control the bus simultaneously. This feature allows for
complex applications with multiprocessor control. It can also be used for rapid testing and alignment of
end products using external connections to an assembly line computer.

I
connected to these two signals must have open drain or open collector outputs. The logic AND function is
exercised on both lines with external pullup resistors.
The default state of I
responding to a slave transmit address, the I
receiver.

A standard communication is composed of four parts:
They are described briefly in the following sections and shown in

C module uses a serial data line (SDA) and a serial clock line (SCL) for data transfer. All devices
1. START signal
2. Slave address transmission
3. Data transfer
4. STOP signal

C system is a true multimaster bus including collision detection and arbitration that prevents data

C pull-up resistors will need to be kept at a relatively low impedance, which may cause noise
