To use the I
C bus function, use the P38/SDA0 and P39/SCL0 pins as the serial transmit/receive data I/O pin
(SDA0) and the serial clock I/O pin (SCL0), respectively.

This mode is used when serial transfers are not performed.

(2) I
C bus mode (multimaster supported)
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 state and data by hardware. This function can simplify
