8 / 24 page 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/S24 and KS2/S25 output pins are selected for key scan output. No. 7135-8/24 LC75863E, 75863W Control data Mode OSC oscillator Segment outputs Output pin states during key scan standby S0 S1 Common outputs KS1 KS2 KS3 KS4 KS5 KS6 0 0 Normal Operating Operating H H H H H H 0 1 Sleep Stopped L L L L L L H 1 0 Sleep Stopped L L L L L H H 1 1 Sleep Stopped L H H H H H H 2. K0, K1 : Key scan output /segment output selection data These control data bits switch the functions of the KS1/S24 and KS2/S25 output pins between key scan output and segment output. X: don’t care Note: KSn(n=1 or 2) : Key scan output Sn (n=24 or 25): Segment output Control data Output pin state Maximum number of K0 K1 KS1/S24 KS2/S25 input keys 0 0 KS1 KS2 30 0 1 S24 KS2 25 1 X S24 S25 20 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. Note: Sn(n=1 to 4): Segment output port Pn(n=1 to 4): 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 D10 is 1, and will output a low level (Vss) when D10 is 0.
