LC75878E, 75878W Control Data Functions 1. PC1 to PC4: General-purpose output port state setting data These control data bits set the states of the general-purpose output ports P1 to P4.
Output pin General-purpose output port state setting data P1 PC1 P2 PC2 P3 PC3 P4 PC4
For example, if PC1 and PC2 are set to 1, and PC3 and PC4 are set to 0, then the output pins P1 and P2 will output high levels (VDD) and the output pins P3 and P4 will output low levels (VSS). 2.

CTC: Display contrast adjustment circuit state setting
CTC 0 1 Display contrast adjustment circuit state The display contrast adjustment circuit is disabled, and the VLCD0 pin level is forced to the VLCD level. The display contrast adjustment circuit operates and the display contrast is adjusted.
Note that although the display contrast can be adjusted by operating the built-in display contrast adjustment circuit, it is also possible to apply fine adjustments to the contrast by connecting an external variable resistor to the VLCD4 pin and modifying the VLCD4 pin voltage. However, the following conditions must be met: (VLCD0 - VLCD4) 4.5 V, and 1.5 V VLCD4 0 V.

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.

BU 0 1 Normal mode Power saving mode The common and segment pins go to the VLCD4 level and the oscillator on the OSC pin is stopped. Note that the states of the general-purpose output ports P1 to P4 are set by PC1 to PC4 in the control data during power saving mode as well as normal mode. Mode

LC75878E, 75878W The INH Pin and Display Control Since the IC internal data (the display data and the control data) is undefined when power is first applied, applications should set the INH pin low at the same time as power is applied to turn off the display (This sets the S1 to S73, S74/COM10, S75/COM9, and COM1 to COM8 to the VLCD4 level and the P1 to P4 to the VSS level.) and during this period send serial data from the controller. The controller should then set the INH pin high after the data transfer has completed. This procedure prevents meaningless displays at power on. (See figures 3, 4, and 5.) Power Supply Sequence The following sequences must be observed when power is turned on and off. (See figures 3, 4, and 5.) * Power on :Logic block power supply(VDD) on LCD driver block power supply(VLCD) on * Power off:LCD driver block power supply(VLCD) off Logic block power supply(VDD) off However, if the logic and LCD driver blocks use a shared power supply, then the power supplies can be turned on and off at the same time. * 1/8 duty
