INSTRUCTION DESCRIPTION Outline overcome speed difference between internal clock KS0070B clock, KS0070B performs internal operations storing control information internal operation determined according signal from MPU, composed read/write data (Refer Table Instruction divided largely into four kinds: KS0070B function instructions display methods, data length, etc.) address instructions internal data transfer instructions with internal others address internal automatically increased decreased NOTE: During internal operation, Busy Flag (DB7) read "1". Busy Flag check must preceded next instruction. When make program with checking Busy Flag (DB7), must necessary Fosc executing next instruction falling signal after Busy Flag (DB7) goes "0". Contents Clear Display
Clear display data writing "20H" (space code) DDRAM addresses, DDRAM addresses "00H" (address counter). Return cursor original status, namely, bring cursor left edge first line display. Make entry mode increment (I/D "1").
Return Home
Return Home cursor return home instruction. DDRAM address "00H" address counter. Return cursor original site return display original status, shifted. Contents DDRAM does change.
KS0070B
16COM 80SEG DRIVER CONTROLLER MATRIX
Entry Mode
moving direction cursor display. Increment decrement DDRAM address (cursor blink) When "1", cursor/blink moves right DDRAM address increased When "0", cursor/blink moves left DDRAM address decreased CGRAM operates same DDRAM, when reading from writing CGRAM. Shift entire display When DDRAM read (CGRAM read/write) operation "0", shift entire display performed. DDRAM write operation, shift entire display performed according value (I/D shift left, shift right).
Display ON/OFF Control
Control display/cursor/blink ON/OFF 1-bit register. Display ON/OFF control When "1", entire display turned When "0", display turned off, display data remains DDRAM. Cursor ON/OFF control When "1", cursor turned When "0", cursor disappears current display, register retains data. Cursor Blink ON/OFF control When "1", cursor blink which performs alternately between data display characters cursor position. When "0", blink off.

Cursor Display Shift
Without writing reading display data, shift right/left cursor position display. This instruction used correct search display data.(Refer Table During 2-line mode display, cursor moves line after 40st digit line. Note that display shift performed simultaneously lines. When displayed data shifted repeatedly, each line shifts individually. When display shift performed, contents address counter changed.
Table Shift Patterns According bits Operation Shift cursor left, decreased Shift cursor right, increased Shift display left, cursor moves according display Shift display right, cursor moves according display
Function
Interface data length control When "1", means 8-bit mode with MPU. When "0", means 4-bit mode with MPU. speak, signal select 8-bit 4-bit mode. When 4-bit mode, needs transfer 4-bit data parts. Display line number control When "0", means 1-line display mode. When "1", 2-line display mode set. Display font type control When "0", dots format display mode When "1", dots format display mode.

Write data
Write binary 8-bit data DDRAM/CGRAM. selection from DDRAM, CGRAM, previous address instruction DDRAM address set, CGRAM address set. instruction also determine direction RAM. After write operation, address automatically increased/decreased according entry mode.
Read data from
Read binary 8-bit data from DDRAM/CGRAM. selection previous address instruction. address instruction performed before this instruction, data that read first invalid, because direction determined. read data several times without address instruction before read operation, correct data from second, first data would incorrect, because there time margin transfer data. case DDRAM read operation, cursor shift instruction plays same role DDRAM address instruction; also transfers data output data register. After read operation address counter automatically increased/decreased according entry mode. After CGRAM read operation, display shift executed correctly. case write operation, after this increased/decreased like read operation. this time, indicates next address position, read only previous data read instruction.
