Description
R/W
The input pin with a pull-up resistor to select Read (“H”) or Write (“L”) in the Parallel I/F
Mode.
This pin should be open in the Serial l/F Mode.
RS
0, RS1
The input pins with a pull-up resistor to select a register in the Parallel l/F Mode.
This pin should be open in the Serial I/F Mode.
E
The input pin for data input/output between the CPU and the ML9044 and for
activating instructions in the Parallel l/F Mode.
This pin should be open in the Serial l/F Mode.
DB
0 to DB3
The input/output pins to transfer data of lower-order 4 bits between the CPU and the
ML9044 in the Parallel l/F Mode. The pins are not used for the 4-bit interface and
serial interface.
Each pin is equipped with a pull-up resistor, so this pin should be open when not used.
DB
4 to DB7
The input/output pins to transfer data of upper 4 bits between the CPU and the
ML9044 in the Parallel l/F Mode. The pins are not used for the serial interface.
Each pin is equipped with a pull-up resistor, so this pin should be open in the Serial I/F
Mode when not used.
OSC
1
OSC
2
OSC
R
The clock oscillation pins required for LCD drive signals and the operation of the
ML9044 by instructions sent from the CPU.
To input external clock, the OSC
1 pin should be used. The OSCR and the OSC2 pins
should be open.
To start oscillation with an external resistor, the resistor should be connected between
the OSC
1 and OSC2 pins. The OSCR pin should be open.
To start oscillation with an internal resistor, the OSC
2 and OSCR pins should be
short-circuited outside the ML9044. The OSC
1 pin should be open.
COM
1 to COM17
The LCD common signal output pins.
For 1/9 duty, non-selectable voltage waveforms are output via COM
10 to COM17. For
1/12 duty, non-selectable voltage waveforms are output via COM
13 to COM17.
SEG
1 to SEG120
The LCD segment signal output pins.
RS
