■ Pins of I
2
C Bus Interface
The pins of the I
2
C bus interface are SDAn and SCLn.
● SDAn pin
The SDAn pin is the data I/O pin of the I
2
C bus interface.
When the I
2
C bus interface is enabled (ICCRn:EN = 1), the SDAn pin is automatically set as a
data I/O pin to function as the SDAn pin.
● SCLn pin
The SCLn pin is the serial clock I/O pin of the I
2
C bus interface.
When the I
2
C bus interface is enabled (ICCRn:EN = 1), the SCLn pin is automatically set as a
shift clock I/O pin to function as the SCLn pin.
