16.1 Functions of Serial Interface IIC0
Serial interface IIC0 has the following two modes.
(1) Operation stop mode
(2) I
Figure 16-1 shows a block diagram of serial interface IIC0.
This mode is used when serial transfers are not performed. It can therefore be used to reduce power
consumption.
This mode is used for 8-bit data transfers with several devices via two lines: a serial clock (SCL0) line and a
serial data bus (SDA0) line.
This mode complies with the I
“transfer direction specification”, “data”, and “stop condition” data to the slave device, via the serial data bus.
The slave device automatically detects these received status and data by hardware. This function can simplify
the part of application program that controls the I
Since the SCL0 and SDA0 pins are used for open drain outputs, IIC0 requires pull-up resistors for the serial
clock line and the serial data bus line.
