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 KS6 key scan
outputs during key scan standby.
Note: This assumes that the KS1/S23 and KS2/S24 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/S23 and KS2/S24 output pins between key scan output and
segment output.

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 (VLCD) when the display data D13 is 1, and will output a low level(VSS) when D13 is 0.
4. SC: Segment on/off control data
This control data bit controls the on/off state of the segments.
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.
