Section 14 I
• Direct bus drive
Clocked synchronous format
• Four interrupt sources
The I/O pins for channel 0 function as NMOS open-drain outputs, and it is possible to apply
voltages in excess of the power supply (P2Vcc) voltage for this LSI. The maximum voltage must
not exceed 0.3 V + this LSI's power supply voltage (P2Vcc). Since the I/O pins for channel 1 are
driven only by NMOS transistors, so in terms of appearance they carry out the same operations as
an NMOS open drain. However, the voltage which can be applied to the I/O pins depends on the
voltage of the power supply (P2Vcc) of this LSI.

Two pins, pins P35/SCL0 and P34/SDA0, function as NMOS open-drain outputs when the bus
drive function is selected.
Two pins, pins P33/SCL1 and P32/SDA1, are driven only by NMOS transistors when the bus
drive function is selected.
