ST7066U  
!"Reset Function  
Initializing by Internal Reset Circuit  
An internal reset circuit automatically initializes the ST7066U when the power is turned on. The  
following instructions are executed during the initialization. The busy flag (BF) is kept in the busy state  
until the initialization ends (BF = 1). The busy state lasts for 40 ms after VCC rises to 4.5 V.  
1. Display clear  
2. Function set:  
DL = 1; 8-bit interface data  
N = 0; 1-line display  
F = 0; 5x8 dot character font  
3. Display on/off control:  
D = 0; Display off  
C = 0; Cursor off  
B = 0; Blinking off  
4. Entry mode set:  
I/D = 1; Increment by 1  
S = 0; No shift  
Note:  
If the electrical characteristics conditions listed under the table Power Supply Conditions Using  
Internal Reset Circuit are not met, the internal reset circuit will not operate normally and will fail  
to initialize the ST7066U. For such a case, initialization must be performed by the MPU as  
explain by the following figure.
