FUNCTION DESCRIPTION

System Interface

This chip has all three kinds interface type with MPU : serial, 4-bit bus and 8-bit bus. Serial and bus(4-bit/8-bit) is selected by

IM input, and 4-bit bus and 8-bit bus is selected by DL bit in the instruction register.

During read or write operation, two 8-bit registers are used. one is data register (DR), the other is instruction register(IR).

The data register(DR) is used as temporary data storage place for being written into or read from DDRAM/CGRAM/SEGRAM,

target RAM is selected by RAM address setting instruction. Each internal operation, reading from or writing into RAM, is done

automatically.

Hence, after MPU reads DR data, the data in the next DDRAM/CGRAM/SEGRAM address is transferred into DR

automatically. Also after MPU writes data to DR, the data in DR is transferred into DDRAM/CGRAM/SEGRAM automatically.

The Instruction register(IR) is used only to store instruction code transferred from MPU. MPU cannot use it to read instruction

data.

To select register, use RS/CS input pin in 4-bit/8-bit bus mode(IM = "High") or RS bit in serial mode(IM = "Low").

Table 2. Various kinds of operations according to RS and R/W bits.

Data Write operation (MPU writes data into DR)

Data Read operation (MPU reads data from DR)

Busy Flag (BF)

When BF = "High", it indicates that the internal operation is being processed. So during this time the next instruction cannot

be accepted. BF can be read, when RS = Low and R/W = High(Read Instruction Operation), through DB7 port.

Before executing the next instruction, be sure that BF is not High.

Timing Generation Circuit

Timing generation circuit generates clock signals for the internal operations.

Address Counter (AC)

Address Counter(AC) stores DDRAM/CGRAM/SEGRAM address, transferred from IR.

After writing into (reading from) DDRAM/CGRAM/SEGRAM, AC is automatically increased

(decreased) by 1. When RS = "Low" and R/W = "High", AC can be read through DB0~DB6

Cursor/Blink Control Circuit

It controls cursor/blink ON/OFF and black/white inversion at cursor position.

LCD Driver Circuit

LCD Driver circuit has 34 common and 120 segment signals for LCD driving.

Data from SEGRAM/CGRAM/CGROM is transferred to 120-bit segment latch serially, which is stored to 120-bit shift latch.

When each common is selected by 34-bit common register, segment data also output through segment driver from 100-bit segment

latch.

In 1-line display mode, COM0 ~ COM17 have 1/17 duty, and in 2-line or 4-line mode, COM0 ~ COM33 have 1/33 duty

ratio.

34COM/120SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD

INSTRUCTION DESCRIPTION

OUTLINE

To overcome the speed difference between internal clock of KS0078 and MPU clock, KS0078 performs internal operation 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 6/10) Instruction can be divided largely four kinds,

(1) KS0078 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 internal RAM is automatically increased or decreased by 1.

When IE = "High", KS0078 is operated according to Instruction Set 1(Table 6) and

when IE = "Low", KS0078 is operated according to Instruction Set 2(Table 10).

* Note : During internal operation, Busy Flag (DB7) is read High. Busy Flag check must precede the next instruction.

When you make a MPU program with checking the Busy Flag(DB7), it must be necessary 1/2Fosc for executing the

next instruction by falling E signal after the Busy Flag(DB7) goes to “Low”.

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 decreased by 1.

* CGRAM/SEGRAM operates the same as DDRAM, when read from or write to CGRAM/SEGRAM.

When S = "High", after DDRAM write, the display of enabled line by DS1 - DS4 bits

in the Shift Enable instruction is shifted to the right (I/D = "0") or to the

left(I/D = "1"). But it will seem as if the cursor does not move.

Without writing or reading of display data, shift right/left cursor position or display.

This instruction is used to correct or search display data.(Refer to Table 7)

During 2-line mode display, cursor moves to the 2nd line after 48th digit of 1st line.

In 4-line mode, cursor moves to the next line, only after every 24th digit of the current line.

Note that display shift is performed simultaneously in all the line enabled by DS1 -

DS4 in the Shift Enable instruction.

When displayed data is shifted repeatedly, each line shifted individually.

When display shift is performed, the contents of address counter are not changed.

During low power consumption mode, display shift may not be performed normally.

HS : Horizontal Scroll per Line Enable

This instruction makes valid dot shift by a display line unit.

HS1, HS2, HS3 and HS4 indicate each line to be dot scrolled, and each scroll is performed individually in each line.

If the line in 1-line display mode or the 1st line in 2-line display mode is to be scrolled, set HS1 and HS2 to "High".

If the 2nd line scroll is needed in 2-line mode, set HS3 and HS4 to "High". (refer to Table 8)

DS : Display Shift per Line Enable

This instruction selects shifting line to be shifted according to each line mode in display shift right/left instruction.

DS1, DS2, DS3 and DS4 indicate each line to be shifted, and each shift is performed individually in each line.

If DS1 and DS2 is set to "High" (enable) in 2 line mode, only the 1st line is shifted

and the 2nd line is not shifted. When only DS1 = "High", only the half of the 1st line is shifted. If all the DS bits

(DS1 to DS4) are set to "Low" (disable), no display is shifted.

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.

In 4-bit bus mode, it is required to transfer 4-bit data by two times.

N : Display line number control bit

It is variable only when NW bit of extended function set instruction is Low.

When N = "Low", it means 1-line display mode.

When N = "High", 2-line display mode is set.

When NW = "High", N bit is invalid, it means 4-line mode independent of N bit.

RE : Extended function registers enable bit

At this instruction, RE must be "Low".

DH : Display shift enable selection bit.

When DH = "High", enable display shift per line.

When DH = "Low", enable smooth dot scroll.

This bit can be accessed only when IE pin input is "High".

REV : Reverse enable bit

When REV = "High", all the display data are reversed. i.e. all the white dots become

black and black dots become white.

When REV = "Low", the display mode set normal display.

Read binary 8-bit data from DDRAM/CGRAM/SEGRAM.

The selection of RAM is set by the previous address set instruction. If address set instruction

of RAM is not performed before this instruction, the data that read first is invalid, as the

direction of AC is not determined. If you read RAM data several times without RAM address

set instruction 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 DDRAM read operation, cursor shift instruction plays the same role as

DDRAM address set instruction : it also transfer RAM data to output data register.

After read operation address counter is automatically increased/decreased by 1 according

to the entry mode. After CGRAM/SEGRAM read operation, display shift may not be executed correctly.

* In case of RAM write operation, AC is increased/decreased by 1 as in read operation after this. In this

time, AC indicates the next address position, but the previous data can only be read by read instruction.

The selection of RAM is set by the previous address set instruction. If address set instruction of RAM is not performed before

this instruction, the data that read first is invalid, as the direction of AC is not determined. If the RAM data is read several

times without RAM address set instruction before read operation, the correct RAM data 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 transfer RAM data to output

data register. After read operation address counter is automatically increased/decreased by 1 according to the entry mode.

After CGRAM/SEGRAM read operation, display shift may not be executed correctly.

* In case of RAM write operation, AC is increased/decreased by 1 like read operation after this. In this time, AC indicates the next

address position, but the previous data can only be read by read instruction.

INTERFACE WITH MPU

KS0078 can transfer data in bus mode (4-bit or 8-bit) or serial mode with MPU. Hence, both types of 4 or 8-bit MPU can be used.

In case of 4-bit bus mode, data transfer is performed by twice to transfer 1 byte data.

(1) When interfacing data length are 4-bit, only 4 ports, from DB4 to DB7, are used as data bus.

At first higher 4-bit (in case of 8-bit bus mode, the contents of DB4 - DB7) are transferred, and then lower 4-bit (in case of 8-bit

bus mode, the contents of DB0 - DB3) are transferred. So transfer is performed by twice. Busy Flag outputs "High" after

the second transfer is ended.

(2) When interfacing data length are 8-bit, transfer is performed at a time through 8 ports, from DB0 to DB7.

(3) If IM is set to "Low", serial transfer mode is set.

Interface with MPU in Serial Mode

When IM port input is "Low", serial interface mode is started. At this time, all three ports, SCLK (synchronizing transfer clock),

SID (serial input data), and SOD (serial output data), are used. If KS0078 is to be used with other chips, chip select port

(CS) can be used.

By setting CS to "Low", KS0078 can receive SCLK input. If CS is set to "High", KS0078 reset the internal transfer counter.

Before transfer real data, start byte has to be transferred. It is composed of succeeding 5 "High" bits, read write control bit

(R/W), register selection bit (RS), and end bit that indicates the end of start byte. Whenever succeeding 5 "High" bits are

detected by KS0078, it makes serial transfer counter reset and ready to receive next information.

The next input data are register selection bit that determine which register will be used, and read write control bit that

determine the direction of data. Then end bit is transferred, which must have "Low" value to show the end of start byte.

(Refer to Fig 13. Fig 14)

(1) Write Operation (R/W = 0)

After start byte is transferred from MPU to KS0078, 8-bit data is transferred which is divided into 2 bytes, each byte has 4 bit's

real data and 4 bit's partition token data. For example, if real data is "10110001" (D0 - D7), then serially transferred data

becomes "1011 0000 0001 0000" where 2nd and 4th 4 bits must be "0000" for safe transfer.

To transfer several bytes continuously without changing RS bit and R/W bit, start byte transfer is needed only at first starting

time. i.e., after first start byte is transferred, real data succeeding can be transferred.

(2) Read Operation (R/W = 1)

After start byte is transferred to KS0078, MPU can receive 8-bit data through the SOD port at a time from the LSB. Wait time

is needed to insert between start byte and data reading, as internal reading from RAM requires some delay.

Continuous data reading is possible such as serial write operation. It also needs only one start bytes, only if you insert some

delay between reading operations of each byte. During the reading operation, KS0078 observes succeeding 5 "High" from

MPU. If it is detected, KS0078 restarts serial operation at once and ready to receive RS bit. So in continuous reading

operation, SID port must be "Low".

INITIALIZING

1) Initializing by Internal Reset Circuit

When the power is turned on, KS0078 is initialized automatically by power on reset circuit.

During the initialization, the following instructions are executed, and BF(Busy Flag) is kept "High"(busy state) to the end

of initialization.

c Display Clear instruction

Write "20H" to all DDRAM

d Set Functions instruction

DL = 1 : 8-bit bus mode

N

= 1 : 2-line display mode

RE = 0 : Extension register disable

BE = 0 : CGRAM/SEGRAM blink OFF

DH = 0 : Horizontal scroll enable

REV = 0 : Normal display (Not reversed display)

e Control Display ON/OFF instruction

D = 0 : Display OFF

C = 0 : Cursor OFF

B = 0 : Blink OFF

f Set Entry Mode instruction

I/D = 1 : Increment by 1

S

= 0 : No entire display shift

BID = 0 : Normal direction segment port

g Set Extension Function instruction

FW = 0 : 5-dot font width character display

B/W = 0 : Normal cursor (8th line)

NW = 0 : Not 4-line display mode, 2-line mode is set because of N("1")

h Enable Shift instruction

HS = 0000 : Scroll per line disable

DS = 0000 : Shift per line disable

i Set scroll Quantity instruction

SQ = 000000 : Not scroll

2) Initializing by Hardware RESET input

When RESET pin = "Low", KS0078 can be initialized like the case of power on reset.

During the power on reset operation, this pin is ignored.

1. Boosted output voltage should not exceed the maximum value (13 V) of the LCD driving voltage.

Especially, a voltage of over 4.3V should not be input to the reference voltage

(Vci) when boosting three times.

2. A voltage of over 5.5V should not be input to the reference voltage (Vci) when boosting

twice.

3. The value of resistance, according to the number of lines, duty ratio and the bias, is

shown below. (Refer to Table 13)
