Pin Description
Pin
Function
I/O
Connected to 2.2~ 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.
Especially, K3 is the input pin for VPP.
For programming K3 pin receives 12.5V(programming voltage).
K0 ~ K3
Input
GND

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.
STOP mode is released by "L" input of each pin.
High current output port
The output is in the form of C-MOS.
The state of large current on is “ H “
