Control Data Functions
1. FC0 to FC2: Common/segment output waveform frame frequency control data
These control data bits set the frame frequency of the common and segment output waveforms.

2. P0 to P2: Segment output port/general-purpose output port switching control data
These control data bits switch the segment output port/general-purpose output port functions of the S1/P1 to S4/P4
output pins.

Note: Sn (n = 1 to 4): Segment output ports
Pn (n = 1 to 4): General-purpose output ports
Note that when the general-purpose output port function is selected, the correspondence between the output pins and
the display data will be that shown in the table.

S3/P3
D9
S4/P4
D13
For example, if the general-purpose output port function is selected for the S4/P4 output pin, that output pin will
output a high level (VDD) when the display data D13 is 1, and a low level (VSS) when the D13 is 0.
3. OC: RC oscillator operating mode/external clock operating mode switching control data.
This control data bit switches the OSC pin function
(either RC oscillator operating mode or external clock operating mode).
OC OSC pin function
0 RC oscillator operating mode
1 External clock operating mode
Note: An external resistor, Rosc, and an external capacitor, Cosc, must be connected to the OSC pin if RC oscillator
operating mode is selected.
4. SC: Segment on/off control data
This control data bit controls the on/off state of the segments.
SC Display state
0 On
1 Off
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.
