INITIALIZING & POWER SAVE MODE SETUP
HARDWARE RESET
When RESETB pin = "Low", S6A0092 can be initialized as 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
VC = 0: Voltage converter OFF
VF = 0: Voltage follower OFF
(4) Function Set instruction
N = 0: 2 Line display mode
S = 0: COM Left shift
CG = 0: CGRAM is not used.
(5) Return Home
Address counter = 00h
(6) Electronic Contrast Control Register: 10h = (0, 0, 0, 0, 0)
(7) In Case of 4-bit Interface Mode Selection
S6A0092 considers the first 4-bit data from MPU as the high order bits.
