16COM / 80SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD
INSTRUCTION DESCRIPTION
Outline
To overcome the speed difference between the internal clock of KS0070B and the MPU clock, KS0070B performs
internal operations by storing control information to IR or DR. The internal
operation is determined according to the signal from MPU, composed of read/write and data bus
(Refer to Table 5 ).
Instruction can be divided largely into four kinds:
(1) KS0070B 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 "1". Busy Flag check must be preceded by the
next instruction.
When you make an MPU program with checking the Busy Flag (DB7), it must be necessary
1/2 Fosc for executing the next instruction by falling E signal after the Busy Flag (DB7) goes to "0".
Contents
1) Clear Display
Clear all the display data by writing "20H" (space code) to all DDRAM addresses, and set the DDRAM addresses
to "00H" in the AC (address counter). Return cursor to original status, namely, bring the cursor to the left edge on
first line of the display. Make entry mode increment (I/D = "1").
2) Return Home
Return Home is the cursor return home instruction.
Set DDRAM address to "00H" in the address counter. Return cursor to its original site and return display to its orig-
inal status, if shifted. Contents of DDRAM does not change.
