19.5.1 Pin configuration
resistor is required.
702
The serial clock pin (SCL0n) and serial data bus pin (SDA0n) are configured as follows (n = 0 to 2).
SCL0n ................This pin is used for serial clock input and output.
SDA0n ................This pin is used for serial data input and output.
Since outputs from the serial clock line and the serial data bus line are N-ch open-drain outputs, an external pull-up
