Instruction description
Outline
To overcome the speed difference between the internal clock of KS0066U and the MPU clock, KS0066U performs internal operations by storing control in formations to IR or DR. The internal operation is determined according to the signal from MPU, composed of read/write and data bus (Refer to Table7). Instructions can be divided largely into four groups: 1) KS0066U function set instructions (set display methods, set data length, etc.) 2) Address set instructions to internal RAM 3) Data transfer instructions with internal RAM 4) Others The address of the internal RAM is automatically increased or decreased by 1. Note: during internal operation, busy flag (DB7) is read "High". Busy flag check must be preceded by the next instruction. Newhaven Display International, LLC 4/9

Contents
1) Clear display RS 0 R/W 0 DB7 0 DB6 0 DB5 0 DB4 0 DB3 0 DB2 0 DB1 0 DB0 1
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 the fist line of the display. Make the entry mode increment (I/D="High").

2) Return home RS 0 R/W 0 DB7 0 DB6 0 DB5 0 DB4 0 DB3 0 DB2 0 DB1 1 DB0 -
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. 3) Entry mode set RS 0 R/W 0 DB7 0 DB6 0 DB5 0 DB4 0 DB3 0 DB2 1 DB1 I/D DB0 SH
Set the moving direction of cursor and display. I/D: increment / decrement of DDRAM address (cursor or blink) When I/D="high", cursor/blink moves to right and DDRAM address is increased by 1. When I/D="Low", cursor/blink moves to left and DDRAM address is increased by 1. *CGRAM operates the same way as DDRAM, when reading from or writing to CGRAM. SH: shift of entire display When DDRAM read (CGRAM read/write) operation or SH="Low", shifting of entire display is not performed. If SH ="High" and DDRAM write operation, shift of entire display is performed according to I/D value. (I/D="high". shift left, I/D="Low". Shift right). 4) Display ON/OFF control RS 0 R/W 0 DB7 0 DB6 0 DB5 0 DB4 0 DB3 1 DB2 D DB1 C DB0 B
Control display/cursor/blink ON/OFF 1 bit register. D: Display ON/OFF control bit When D="High", entire display is turned on. When D="Low", display is turned off, but display data remains in DDRAM. C: cursor ON/OFF control bit When D="High", cursor is turned on. When D="Low", cursor is disappeared in current display, but I/D register preserves its data. B: Cursor blink ON/OFF control bit When B="High", cursor blink is on, which performs alternately between all the "High" data and display characters at the cursor position. When B="Low", blink is off. 5) Cursor or display shift RS 0 R/W 0 DB7 0 DB6 0 DB5 0

Shifting of right/left cursor position or display without writing or reading of display data. 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 S/C 0 0 1 1 R/L 0 1 0 1 Operation Shift cursor to the left, AC is decreased by 1 Shift cursor to the right, AC is increased by 1 Shift all the display to the left, cursor moves according to the display Shift all the display to the right, cursor moves according to the display
6) Function set RS 0 R/W 0 DB7 0 DB6 0 DB5 1 DB4 DL DB3 N DB2 F DB1 DB0 -
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 0 R/W 0 DB7 0 DB6 1 DB5 AC5 DB4 AC4 DB3 AC3 DB2 AC2 DB1 AC1 DB0 AC0
Set CGRAM address to AC. The instruction makes CGRAM data available from MPU. 8) Set DDRAM address RS 0 R/W 0 DB7 1 DB6 AC6 DB5 AC5 DB4 AC4 DB3 AC3 DB2 AC2 DB1 AC1 DB0 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 0 R/W 1 DB7 BF DB6 AC6 DB5 AC5 DB4 AC4 DB3 AC3 DB2 AC2 DB1 AC1 DB0 AC0
This instruction shows whether KS0066U 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 1 R/W 0 DB7 D7 DB6 D6 DB5 D5 DB4 D4 DB3 D3 DB2 D2 DB1 D1 DB0 D0
Write binary 8-bit data to DDRAM/CGRAM. The selection of RAM from DDRAM, and CGRAM, is set by the previous address set instruction (DDRAM address set, CGRAM address set). RAM set instruction can also determine the AC direction to RAM. After write operation. The address is automatically increased/decreased by 1, according to the entry mode. 11) Read data from RAM RS 1 R/W 1 DB7 D7 DB6 D6 DB5 D5 DB4 D4 DB3 D3 DB2 D2 DB1 D1 DB0 D0
Read binary 8-bit data from DDRAM/CGRAM. The selection of RAM is set by the previous address set instruction. If the address set instruction of RAM is not performed before this instruction, the data that has been read first is invalid, as the direction of AC is not yet determined. If RAM data is read several times without RAM address instructions set before, read operation, the correct RAM data can be obtained from the second. But the first data would be incorrect, as there is no time margin to transfer RAM data. In case of DDRAM read operation, cursor shift instruction plays the same role as DDRAM address set instruction, it also transfers RAM data to output data register. After read operation, address counter is automatically increased/decreased by 1 according to the entry mode. After CGRAM read operation, display shift may not be executed correctly. NOTE: In case of RAM write operation, AC is increased/decreased by 1 as in read operation. At this time, AC indicates next address position, but only the previous data can be read by the read instruction.
