• INT3/ SDA – Port C, Bit3
INT3: External Interrupt Source 3. This pin can serve as external interrupt source. INT3 can be
used as an interrupt pin regardless of whether another function is enabled or not.
SDA: SM Bus Data. This pin can serve as bidirectional serial data line for the 2-wire Serial
Interface.
• SCL – Port C, Bit4
SCL: SM Bus Clock. This pin can serve as bidirectional clock line for the 2-wire Serial Interface
