n Reset Function

Initializing by Internal Reset Circuit

An internal reset circuit automatically initializes the ST7032 when the power is turned on. The following

instructions are executed during the initialization. The busy flag (BF) is kept in the busy state (BF = 1) until the

initialization ends. The busy state lasts for 40 ms after VDD rises to stable.

Display clear

Function set:

DL = 1; 8-bit interface data

N = 0; 1-line display

DH=0; normal 5x8 font

IS=0; use instruction table 0

Display on/off control:

D = 0; Display off

C = 0; Cursor off

B = 0; Blinking off

Entry mode set:

I/D = 1; Increment by 1

S = 0; No shift

Internal OSC frequency

(F2,F1,F0)=(1,0,0)

ICON control

Ion=0; ICON off

Power control

BS=0; 1/5bias

Bon=0; booster off

Fon=0; follower off

(C5,C4,C3,C2,C1,C0)=(1,0,0,0,0,0)

(Rab2,Rab1,Rab0)=(0,1,0)

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

ST7032.

When internal Reset Circuit not operate, ST7032 can be reset by XRESET pin from MPU control signal.
