Termination of common pins
I/O ports:
Select an input port or an output port and follow
each processing method.
In addition, it is recommended that related
registers be overwritten periodically to prevent
malfunctions, etc.
Output ports: Open.
Input ports:
If the input level become unstable, through current
flow to an input circuit, and the power supply
current may increase.
Especially, when expecting low consumption
current (at STP or WIT instruction execution etc.),
pull-up or pull-down input ports to prevent
through current (builtin resistor can be used).
We recommend processing unused pins through a
resistor which can secure IOH(avg) or IOL(avg).
Because, when an I/O port or a pin which have an
output function is selected as an input port, it may
operate as an output port by incorrect operation
etc.

Set to the input mode and connect each to VCC or VSS through a resistor of 1 k
to 10 k.
Set to the output mode and open at “L” or “H” output state.
VREF
Connect to VCC or VSS (GND).
AVSS
Connect to VCC or VSS (GND).
XOUT
Open (only when using external clock)
