I/O
I Reference voltage input of A/D converter.
I Analog input of A/D converter.
I A/D external trigger input.
I/O Expansion analog input of A/D converter, and output of external ope-amplifier
connection mode.
I Expansion analog input of A/D converter.
I/O 8 bits I/O port of the CMOS.
Have a direction register to select input and output, and can do it to an input port
or an output port every 1 terminal.
The input port can select having pulling up resistance or not by a 4 bits unit by a
program.
(but the output of P7_0, P7_1 is N channel open drain.)
I/O I/O port with the function that is equal to P0.

Use a terminal in common with NMI.
Port for exclusive use of the input to confirm a level of NMI.
