Pin Description
Pin
Function
I/O
Connected to 2.0~ 3.6V power supply
Connected to 0V power supply.
4-bit input port with built in pull-up resistor.
STOP mode is released by "L" input of each pin. ( masked option)
K0 ~ K3
Input

Each can be set and reset independently.
The output is the structure of N-channel-open-drain.
4-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.
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. The output is in the form of CMOS.
The state of large current on is "H".
D0 ~ D9
