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, namely, bring the cursor to the left edge on first
line of the display. Make entry mode increment (I/D = "1").

Return Home is 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.

PD
Power down mode enable bit set instruction. When PD = "High", it makes S6A0075 suppress current
consumption except the current needed for data storage by executing next three functions.
• Make the output value of all the COM/SEG ports VDD
• Make the COM/SEG output value of extension driver VDD by setting D output to "High" and M output to
"Low"
• Disable voltage converter to remove the current through the divide resistor of power supply.
You can use this instruction as power sleep mode.
When PD = "Low", power down mode becomes disabled.
