ML9040A-Axx/-Bxx
Semiconductor
24/49
PEDL9040A-03
Built-in Reset Circuit
The ML9040A-Axx/-Bxx is automatically initialized when the power is turned on.
During initialization, the busy flag (BF) holds "H" and does not accept instructions (other
than the busy flag read).
The busy flag holds "H" for 15 ms after VDD reaches 4.5V or more.
During initialization, the ML9040A-Axx/-Bxx executes the follwing instructions:
Display clear
Data length of interface with CPU: 8 bits (8B/4B = "H")
LCD: 1-line display (N = "L")
Character font: 5 x 7 dots (F = "L")
ADC: Increment (I/D = "H")
No display shift (SH = "L")
Display: Off (DI = "L")
Cursor: Off (C = "L")
No blink (B = "L")
It is required to satisfy the following power supply conditions.
