MSM6222B-xx

Built-in Reset Circuit

The MSM6222B-xx 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 MSM6222B-xx 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.
