Overview

The I2C module is designed to be a master and slave. The slave is active only when

the module is being addressed during an I2C bus transfer; the master can arbitrate for

and access the I2C bus only when the bus is free (idle) — therefore, the master and

slave are mutually exclusive.

Physical I2C bus

The physical I2C bus consists of two open-drain signal lines: serial data (SDA) and

serial clock (SCL). Pullup resistors are required; see the standard I2C bus specification

for the correct value for the application. Each device connected to the bus is

software-addressable by a unique 7- or 10-bit address, and a simple master/slave

relationship exists at all times.

A master can operate as a master-transmitter (writes)) or a master-receiver (reads).

The slaves respond to the received commands accordingly:

In transmit mode (slave is read), the host interface receives character-

based parallel data from the ARM. The module converts the parallel data to

serial format and transmits the serial data to the I2C bus.

In receive mode (slave is written to), the I2C bus interface receives 8-bit-

based serial data from the I2C bus. The module converts the serial data to

parallel format and interrupts the host. The host’s interrupt service routine

reads the parallel data from the data register inside the I2C module. The

serial data stream synchronization and throttling are done by modulating the

serial clock. Serial clock modulation can be controlled by both the

transmitter and receiver, based in their hosts’ service speed.

The I2C is a true multi-master bus with collision detection and arbitration to prevent

data corruption when two or more masters initiate transfer simultaneously. If a

master loses arbitration during the addressing stage, it is possible that the winning

master is trying to address the transfer. The losing master must therefore

immediately switch over to its slave mode.

The on-chip filtering rejects spikes on the bus data line to preserve data integrity.

The number of ICs that can be connected to the same bus is limited only by a

maximum bus capacity of 400 pf.
