Pin Functions
Oscillator connection.
An oscillator circuit is formed by connecting an external resistor and
capacitor at this pin.
Serial data transfer inputs.
These pins are connected to the microcontroller.
CE :Chip enable
CL :Synchronization clock
DI :Transfer data
L
Input that turns the display off and forces the general-purpose output
ports low.
When INH is low (V
SS
)
Display off
S1 to S73 = “L” (V
LCD

S74/COM10, S75/COM9 = “L” (V
LCD

COM1 to COM8 = “L” (V
LCD
4).
General-purpose output ports P1 to P4 = low (V
SS
)
When INH is high (V
DD
)
Display on
The states of the general-purpose output ports can be set by
the PC1 to PC4 control data.
However, serial data can be transferred when the INH pin is low.
LCD drive 3/4 bias voltage (middle level) supply pin. This pin can be
used to supply the 3/4 (V
LCD
0 – V
LCD
4) voltage level externally.
LCD drive 2/4 bias voltage (middle level) supply pin. This pin can be
used to supply the 2/4 (V
LCD
0 – V
LCD
4) voltage level externally.
LCD drive 1/4 bias voltage (middle level) supply pin. This pin can be
used to supply the 1/4 (V
LCD
0 – V
LCD
4) voltage level externally.
LCD drive 0/4 bias voltage (low level) supply pin. Fine adjustment of the
display contrast can be implemented by connecting an external variable
resistor to this pin.
However, (V
LCD
0 – V
LCD
4) must be greater than or equal to 4.5 V, and
V
LCD
4 must be in the range 0 V to 1.5 V, inclusive.
Logic block power supply connection. Provide a voltage of between 2.7
and 6.0V.
LCD driver block power supply connection. Provide a voltage of between
7.0 and 11.0 V when the display contrast adjustment circuit is used and
provide a voltage of between 4.5 and 11.0 V when the circuit is not used.
LCD drive 4/4 bias voltage (high level) supply pin. The level on this pin
can be changed by the display contrast adjustment circuit.
However, (V
LCD
0 – V
LCD
4) must be greater than or equal to 4.5 V.
Also,external power must not be applied to this pin since the pin circuit
includes the display contrast adjustment circuit.
