Set Power Save Mode / Oscillator Control
To enter Standby or Sleep Mode, it should be done by turning off the internal oscillator and turning on the power
save control bit. The corresponding control bits are X
1
X
0
= 01. In order to put the system into low power consumption
mode, internal voltage converter, voltage regulator and voltage divider should also be turned off by using Power
Control Register. After putting the system into power save mode, the following status will be entered:
1. Internal oscillator and LCD power supply circuits are stopped.
2. Segment and Common drivers output AV
SS
level.
3. The display data and operation mode before sleep are held. All the internal circuit are stopped.
Function Set
This command sets 3 functions on the system. They are the number of display line (2 or 3), COM shift direction
(left or right) and CGROM/ CGRAM character area select.
Set Display Start Line
This command is to set Display Start Line register to determine starting address of display data RAM to be
displayed by selecting a value from 0 to 3. With the value equals to 0, the display will start from address (00h-0Fh).
With the value equals to 1, the display will start from address (10h-1Fh). With the value equals to 2, the display will
start from address (20h-2Fh). With the value equals to 3, the display will start from address (30-3Fh).
Set Bias Control
Bias ratio 1/4 or 1/5 could be set using this command. When changing the number of line display, the bias ratio
also needs to be adjusted to make display contrast consistent.
Set Power Control Register
This command turns on / off the various power circuits associated with the chip which including regulated DC-DC
converter and voltage divider.
Set Display Control
This command provides 3 display functions. It turns on/off both the cursor, blink and display. When both cursor
and blink control bit set high, the driver make LCD alternate between inverting display character and normal display
character at the cursor position with about a half second. On the contrary, if cursor control bit is low, only a normal
character is displayed regardless of blink control bit.
