LC75806PT
Control Data Functions
1. OC …RC oscillator operating mode/external clock operating mode switching control data
This control data bit selects the OSC pin function (RC oscillator operating mode or external clock operating mode)
OC

OSC pin function
RC oscillator operating mode
External clock operating mode
Note: If RC oscillator operating mode is selected, connect an external resistor ROSC and an external capacitor COSC
to the OSC pin.
2. PC90, PC91 … General-purpose output port/clock output port/segment output port switching control data
These control data bits swithes the functions of the P9/S77 output pin between the general-purpose output port, the
clock output port, and the segment output port.

Clock output port (P9) (Clock frequency is fOSC/2 or fCK/2)
Segment output port (S77)
Note: If the sleep mode is set, the P5/S57 output pin can not be used as the clock output port.
3. 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
output during key scan standby.

Note: This assumes that the KS1/S75 and KS2/S76 output pins are selected for key scan output.
4. K0, K1 … Key scan output/segment output switching control data
These control data bits switch the functions of the KS1/S75 and KS2/S76 output pins between the key scan output
and the segment output.
