This instruction is used to correct or search display data.
During 2-line mode display, cursor moves to the 2nd line after the 40th digit of the 1st line.
Note that display shift is performed simultaneously in all the lines.
When display data is shifted repeatedly, each line is shifted individually.
When display shift is performed, the contents of the address counter are not changed.
Shift patterns according to S/C and R/L bits
When DL=“High”, it means 8-bit bus mode with MPU.
When DL=“Low”, it means 4-bit bus mode with MPU. Hence, DL is a signal to select 8-bit or 4-bit bus mode.
When 4-but bus mode, it needs to transfer 4-bit data twice.
When N=“Low”, 1-line display mode is set.
When N=“High”, 2-line display mode is set.
When F=“Low”, 5x8 dots format display mode is set.
When F=“High”, 5x11 dots format display mode.
Set CGRAM address to AC.
The instruction makes CGRAM data available from MPU.
Set DDRAM address to AC.
This instruction makes DDRAM data available form MPU.
When 1-line display mode (N=LOW), DDRAM address is form “00H” to “4FH”.In 2-line display mode (N=High),
DDRAM address in the 1st line form “00H” to “27H”, and DDRAM address in the 2nd line is from “40H” to
“67H”.
This instruction shows whether SPLC780D is in internal operation or not.
If the resultant BF is “High”, internal operation is in progress and should wait BF is to be LOW, which by then
the nest instruction can be performed. In this instruction you can also read the value of the address counter.
