I
11.1.1
The two-wire I
bus allows the connection of additional devices to the bus for expansion and system development. The bus
includes collision detection and arbitration that prevent data corruption if two or more masters attempt to
control the bus simultaneously.

C interface includes the following features:
C units on this device can operate in one of the following modes:
Two-wire interface
Multiple-master operation
Arbitration lost interrupt with automatic mode switching from master to slave
Calling address identification interrupt
START and STOP signal generation/detection
Acknowledge bit generation/detection
Bus busy detection
Software-programmable clock frequency
Software-selectable acknowledge bit
On-chip filtering for spikes on the bus
Master mode—The I
address. The I
Slave mode—The I
START condition from a non-I
Interrupt-driven byte-to-byte data transfer—When successful slave addressing is achieved (and
SCL returns to zero), the data transfer can proceed on a byte-to-byte basis in the direction specified
by the R/W bit sent by the calling master. Each byte of data must be followed by an acknowledge
bit, which is signaled from the receiving device. Several bytes can be transferred during a data
transfer session.
Boot sequencer mode—This mode can be used to initialize the configuration registers in the device
after the I
disabled as a default, but this mode can be selected with the cfg_boot_seq[0:1] power-on reset
(POR) configuration signals that are located on the LGPL3 and LGPL5 signals.
