SLS System Logic Semiconductor
Reverse Display ON / OFF
All segments ON / OFF
contents of the display data RAM are held. This instruction has priority over the Reverse Display ON / OFF instruction.
Select LCD Bias
Set Read-Modify-Write
column address is still increased by the write display data instruction. And it reduces the load of microprocessor when
the data of a specific area is repeatedly changed during cursor blinking or others. This mode is canceled by the reset
Modify-read instruction.
Forces the whole LCD points to be turned on regardless of the contents of the display data RAM.At this time, the
Selects LCD bias ratio of the voltage required for driving the LCD.
This instruction stops the automatic increment of the column address by the read display data instruction,but the
Reverses the display status in LCD panel without rewriting the contents of the display data RAM.
