INITIALIZING & POWER SAVE MODE SETUP
HARDWARE RESET
After reset by RES pin, KS0090 can be initialized the following state.
1. Control Display on/off instruction
C=0: Cursor off
B=0: Blink off
D=0: Display off
2. Power Save Set instruction
OS=0: Oscillator off
PS=0: Power save off
3. Power Control Set instruction
VR=0: Voltage regulator off
VF=0: Voltage follower off
VC=0: Voltage converter off
4. Function Set instruction
N2=0, N1=0: 2 line display mode
S=0: COM left shift
CG=0: CGRAM is not used
5. Return Home
Address counter = 30h
6. Static icon RAM & electronic contrast control register
Static icon RAM: 20h = (0, 0, 0, 0, 0), static icon off
21h = (0, 0, 0, 0, 0), blink off
EV = 0: 32 contrast-step
Electronic contrast control register: 28h = ((0),0, 0, 0, 0, 0), contrast high
7.
In case of 4-bit interface mode selection KS0090 considers the first 4-bit data from MPU as the high order bits.
NOTE:
If initialization is not done by the RES pin at application, an unknown condition may result, in which case you can
initialize by instruction.
