Termination of Unused Pins
1. Termination of common pins
I/O ports:
Select an input port or an output port and follow
each processing method.
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 (built-in resistor can be used).
We recommend processing unused pins through a
resistor which can secure IOH(avg) or IOL(avg).

P00/KEY0
P07/KEY7
I/O port
When selecting key-on wakeup function, perform termination of input port.
P10
P11(RLSS-only pin)
When selecting N-channel open-drain for output structure, open.
P20 (LED0)/INT0
When selecting N-channel open-drain for output structure, connect to VSS
through a resistor. Or set its port latch to “0” and open.
P21 (LED1)/INT1
When selecting N-channel open-drain for output structure, connect to VSS
through a resistor. Or set its port latch to “0” and open.
P22 (LED2)
P27 (LED7)
When selecting N-channel open-drain for output structure, open.
P30
P37
When selecting N-channel open-drain for output structure, open.
P40 (LED8) (RLSS-only pin)
P41 (LED9) (RLSS-only pin)
P42/CARR
When selecting CARR output function, perform termination of output port.
VDDR
Connect to VSS.
