Function
Signal ground for LCM (GND)
Power supply for logic (+3.3V) for LCM
Contrast adjust
Register select signal
Read/write select signal
Operation (data read/write) enable signal
Four low order bi-directional three-state data bus lines.
Used for data transfer between the MPU and the LCM.
These four are not used during 4-bit operation.
Four high order bi-directional three-state data bus lines.
Used for data transfer between the MPU
Power supply for BKL
Power supply for BKL

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
S/C R/L
Operation
0 0 Shift cursor to the left, AC is decreased by 1
0 1 Shift cursor to the right, AC is increased by 1
1 0 Shift all the display to the left, cursor moves according to the display
1 1 Shift all the display to the right, cursor moves according to the display
6) Function set
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 1 DL N F - -
DL: Interface data length control bit
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.
N: Display line number control bit
When N=“Low”, 1-line display mode is set.
When N=“High”, 2-line display mode is set.
F: Display line number control bit
When F=“Low”, 5x8 dots format display mode is set.
When F=“High”, 5x11 dots format display mode.
7) Set CGRAM address
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 1 AC5 AC4 AC3 AC2 AC1 AC0
Set CGRAM address to AC.
The instruction makes CGRAM data available from MPU.
8) Set DDRAM address
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 1 AC6 AC5 AC4 AC3 AC2 AC1 AC0
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”.
9) Read busy flag & address
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 1 BF AC6 AC5 AC4 AC3 AC2 AC1 AC0
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.
10) Write data to RAM
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
1 0 D7 D6 D5 D4 D3 D2 D1 D0
