Input (low-level)
Notes 1.
Note that the drive capability of the low-level output side is held low.
2.
In order to prevent malfunction, be sure to input a low level to more than one of pins K
I0
to K
I3
when
POC is released due to supply voltage startup.
These pins refer to the 8-bit I/O ports. I/O switching can
be made in 8-bit units.
In INPUT mode, a pull-down resistor is added.
In OUTPUT mode, they can be used as a key scan output
from key matrix.
Refers to the input port.
Can also be used as a key return input from key matrix.
In INPUT mode, the availability of the pull-down resistor
of the S
0
and S
1
ports can be specified by software in
terms in 2-bit units.
If INPUT mode is canceled by software, this pin is placed
in OFF mode and enters the high-impedance state.
Refers to the I/O port.
In INPUT mode (S
1
), this pin can also be used as a key
return input from key matrix.
The availability of the pull-down resistor of the S
0
and S
1
ports can be specified by software in 2-bit units.
In OUTPUT mode (LED), this pin becomes the remote
control transmission display output (active low). When
the remote control carrier is output from the REM output,
this pin outputs the low level from the LED output
synchronously with the REM signal.
Refers to the infrared remote control transmission output.
The output is active high.

Refers to the power supply.
These pins are connected to system clock ceramic
resonators.
Refers to the ground.
Refers to the input port.
The use of the STOP mode release of the S
2
port can be
specified by software. When using this pin as a key input
from a key matrix, enable the use of the STOP mode
release (at this time, a pull-down resistor is connected
internally.)
When the STOP mode release is disabled, this pin can
be used as the input port which does not release the
STOP mode even if the release condition is established
(at this time, a pull-down resistor is not connected internally.)
These pins refer to the 4-bit input ports.
They can be used as a key return input from key matrix.
The use of the pull-down resistor can be specified by
software in 4-bit units.
