MSM6562B-xx

10. Built-in Reset Circuit
The MSM6562B-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 goes to "H" for 15 ms after V
DD
reaches 4.5V or more.
During initialization, the MSM6562B-xx executes the following instructions :
Display clear
Data length of interface with CPU : 8 bits (8B/4B = "H")
LCD : 1-line display (N = "L")
Character font : 5
￥
7 dots (F = "L")
ADC : increment (I/D = "H")
No display shift (S = "L")
Display : Off (D = "L")
Cursor : Off (C = "L")
No blink (B = "L")
Contrast data : 1F (hex.) set
When the built-in reset circuit is used, the power supply conditions shown in the figure below
must be satisfied. If they are not satisfied, because in that case the built-in reset circuit does not
operate normally, initialize the MSM6562B-xx by instruction through the CPU (see the section
on instruction initialization).
If a battery is used as supply voltage source, be sure to initialize the instruction.
