This pin should be open in the Serial I/F Mode.
The input pin for data input/output between the CPU and the ML9041 and for activating
instructions in the Parallel I/F Mode.
This pin should be open in the Serial I/F Mode.
The input/output pins to transfer data of lower–order 4 bits between the CPU and the
ML9041 in the Parallel I/F Mode. Each pin is equipped with a pull–up resistor. These 4
lines are not used for the 4–bit interface.
This pin should be open in the Serial I/F Mode.
The input/output pins to transfer data of upper 4 bits between the CPU and the ML9041
in the Parallel I/F Mode. Each pin is equipped with a pull–up resistor.
This pin should be open in the Serial I/F Mode.
The clock oscillation pins required for LCD drive signals and the operation of the
ML9041 by instructions sent from the CPU.
To input external clock, the OSC
1
pin should be used. The OSC
R
and the OSC
2
pins
should be open.
To start oscillation with an external resistor, the resistor should be connected between
the OSC
1
and OSC
2
pins. The OSC
R
pin should be open.
To start oscillation with an internal resistor, the OSC
2
and OSC
R
pins should be
short–circuited outside the ML9041. The OSC
1
pin should be open.
The LCD common signal output pins.
For 1/9 duty, non–selectable voltage waveforms are output via COM
10
to COM
17
. For
1/12 duty, non–selectable voltage waveforms are output via COM
13
to COM
17
.
The LCD segment signal output pins.
