Notes 1.
Take into consideration the drive capability and current dissipation of a port when the port is
externally pulled up or down. To pull up or down the port with a high resistance, exercise care
so that noise is not superimposed on the port pin. The appropriate value of the pull-up or pull-
down resistor differs depending on the application circuit. Generally, select a resistor of several
10 k
.
The P0F
0
/RLS pin is also used to set a test mode. When this pin is not used, do not connect a
pull-up resistor to it by mask option, but directly connect it to GND.
In an application circuit where a high reliability is required, be sure to input the RESET signal from
an external source. The RESET pin is also used to set a test mode. When this pin is not used,
directly connect it to V
DD
.

Caution
It is recommended to fix the input/output mode, pull-up resistor by software, and the output
level of the pin by repeatedly setting them in each loop of the program.
Connect on-chip pull-up resistor via
software.
