AMIS−52150
I²C Interface
The I²C is a two pin bi-directional serial interface
communication bus, with a data line and a clock line,
respectively. Serial data on the data pin is clocked into or out
of the AMIS−52150 by the clock pin. The AMIS−52150 is
implemented as a slave device, which means that the
external controller is the master device. The clock signal for
all transmissions between the master (controller) and the
slave (AMIS−52150) is generated by the controller. The
serial communication bit rate can be as high as 400 kbps. A
communication link is initiated based on a start sequence.
Bi-directional communication continues as long as the
master and slave acknowledge the write or read sequences,
and is terminated with a stop sequence. This is illustrated in
Figure 14, Figure 15 and Figure 16, respectively.
