KS0073
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, bringing 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 a cursor return home instruction.
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.
3) Power Down Mode Set: (RE = 1)
Power down mode enable bit set instruction.
PD = “High”, it makes KS0073 suppress current consumption except the current needed for data storage
by executing the next three functions.
1. make the output value of all the COM/SEG ports VDD
2. make the COM/SEG output value of the extension driver VDD by setting D output to “High”
3. disable voltage converter to remove the current through the divide resistor of power
and M output to “Low”
supply.
This instruction can be used as power sleep mode.
When PD = “Low”, power down mode becomes disabled.
