Notes 1 : _{When ports P11–P14 are used as multi-master I} 2_{C-BUS interface pin and when ports P2 0, P21 are used as}
serial I/O output pins, their output structure is N-channel open-drain output.
2 : For the output structure of ports P3 0, P31, either CMOS output or N-channel open-drain output is selected
(In the case of N-channel open-drain output, the block diagram is the same as below).
