5. P0 to P3 … Segment output port/general-purpose output port switching control data
These control data bits switch the functions of the S1/P1 to S8/P8 output pins between the segment output port and
the general-purpose output port.

Note: Sn (n=1 to 8): Segment output port
Pn (n=1 to 8): General-purpose output port
The table below lists the correspondence between the display data and the output pins when these pins are selected to
be general-purpose output ports.

For example, if the circuit is operated in 1/4 duty and the S4/P4 output pin is selected to be a general-purpose output
port, the S4/P4 output pin will output a high level when the display data D13 is 1, and will output a low level when
D13 is 0.
6. SC … Segment on/off control data
This control data bit controls the on/off state of the segments.
SC
0
1
Display state
On
Off
However, note that when the segments are turned off by setting SC to 1, the segments are turned off by outputting
segment off waveforms from the segment output pins.
7. KSC … Key scan operation enabled/disabled state setting control data
This control data bit enables or disables key scan operation.
KSC
0
1
Key scan operating state
Key scan operation enabled
(A key scan operation is performed if any key on the lines corresponding to KS1 to KS6 pin which is set
high is pressed.)
Key scan operation disabled
(No key scan operation is performed, even if any of the keys in the key matrix are pressed.
If this state is set up, the key data is forcibly reset to 0 and the key data read request is also cleared.
(DO is set high.))
