Control Data Functions
1. S0, S1: Sleep control data
These control data bits switch between normal mode and sleep mode and set the states of the KS1 to KS4 key scan
outputs during key scan standby.
Note: This assumes that the KS1/S15 and KS2/S16 output pins are selected for key scan output.

2. K0, K1: Key scan output/segment output selection data
These control data bits switch the functions of the KS1/S15 and KS2/S16 output pins between key scan output and
segment output.
X: don’t care
Note: KSn (n = 1, 2): Key scan output
Sn (n = 15, 16): Segment output
Note: Sn (n = 1 to 4): Segment output port
Pn (n = 1 to 4): General-purpose output port
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.

3. P0 to P2: Segment output port/general-purpose output port selection data
These control data bits switch the functions of the S1/P1 to S4/P4 output pins between the segment output port and
the 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 S4/P4 output pin is selected to be a general-purpose output port, the S4/P4 output pin will output a
high level (VDD) when the display data D10 is 1, and will output a low level (VSS) when D10 is 0.
