KS0078
1) Display Clear
Clear all the display data by writing "20H" (space code) to all DDRAM address, and set DDRAM address to "00H"
into AC (address counter). Return cursor to the original status, hence, bring the cursor to the left edge on first line
of the display. Make entry mode increment (I/D = "1").
2) Return Home : (RE = 0)
Return Home is cursor return home instruction.
3) Power Down Mode Set : (RE = 1)
Power down mode enable bit set instruction.






























When PD = "High", it makes KS0078 suppress current consumption except the current needed for
Set DDRAM address to "00H" into the address counter. Return cursor to its original
site and return display to its original status, if shifted.
Contents of DDRAM does not change.
data storage by executing next three functions.
1. make the output value of all the COM/SEG ports VDD
2. make the COM/SEG output value of extension driver VDD by setting D output to "High"
3. disable voltage converter to remove the current through the divide resistor of power
When PD = "Low", power down mode becomes disabled.

supply.
This instruction can be used as power sleep mode.
