Each can be set and reset independently.
The output is the structure of N-channel-open-drain.
2-bit I/O port. (Input mode is set only when each of them output "H".)
In outputting, each can be set and reset independently(or at once.)
The output is in the form of C-MOS.
STOP mode is released by "L" input of each pin.
Pull-up resistor and STOP release mode can be respectively selected
as masked option for each pin.(It is released by “L” input at STOP)
High current output port for driving I.R.LED.
The output is in the form N-channel open drain.
D0 ~ D6
Output
R2 ~ R3
