FUNCTION DESCRIPTION

System Interface

This chip has both kinds of interface type with MPU: 4-bit bus and 8-bits bus. 4-bit bus and 8-bit bus are selected by the DL bit in the instruction register.

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

The data register (DR) is used as a temporary data storage place for being written into or read from DRAM/CGRAM . Target RAM is selected by RAM address setting instruction. Each internal operation, reading from or writing into RAM, is done automatically. After MPU reads DR data, the data in the next DDRAM/CGRAM address is transferred into DR automatically. Also, after MPU writes data to DR, the data in DR is transferred into DDRAM/CGRAM automatically.

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

To select a register, use RS input pin in 4-bit/8-bit bus mode. Table 1. Various Kinds of Operations to RS and R/W bits.

RS R/W Operation

0 0 Instruction Write operation (MPU writes instruction code into IR) 0 1 Read Busy flag (DB7) and address counter (DB0 - DB7) 1 0 Data Write operation (MPU writes data into DR) 1 1 Data Read operation (MPU reads data into DR)

Busy Flag (BF)

When BF = 1, 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 = 0, and R/W = 1. (Read Instruction Operation), through DB7 port. Before executing the next instruction, be sure that BF is not 1.

80 SEG / 16 COM DRIVER & CONTROLLER FOR DOT MATRIX LCD S6A0070

Address Counter (AC)

The Address Counter (AC) stores DDRAM/CGRAM addresses, transferred from IR. After writing into (reading from) DDRAM/CGRAM. AC is automatically increased (decreased) by 1. When RS = 0 and R/W = 1, AC can be read through ports DB0 - DB6.

Display Data RAM (DDRAM) DDRAM stores display data of maximum 80 x 8 bits (80 characteristics). DDRAM address is set in the address

counter (AC) as a hexadecimal number. (Refer to fig-1).

INSTRUCTION DESCRIPTION

OUTLINE

To overcome the speed difference between internal clock of S6A0070 and MPU clock, S6A0070 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 5) Instruction can be divided largely four kinds,

(1) S6A0070 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.

NOTE: During internal operation, Busy Flag (DB7) is read "1". Busy Flag check must be precede by the next instruction.

When you make an MPU program with checking the Busy Flag (DB7) is made, 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

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

0 0 0 0 0 0 0 0 0 1

Clear all the display data by writing "20H" (space code) to all DDRAM address, and set DDRAM address to "00H" in the AC (address counter). Return cursor to the 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

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

0 0 0 0 0 0 0 0 1 x

Return Home is cursor return home instruction. Set DDRAM address to "00H" in the address counter. Return cursor to its original site and return display to its original status, if shifted. Contents of DDRAM does not change.

S6A0070 80 SEG / 16 COM DRIVER & CONTROLLER FOR DOT MATRIX LCD

3) Entry Mode Set

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

0 0 0 0 0 0 0 1 I/D SH

Set the moving direction of cursor and display. I/D : Increment / decrement of DDRAM address (cursor or blink) When I/D = "1", cursor/blink moves to right and DDRAM address is increased by 1. When I/D = "0", cursor/blink moves to left and DDRAM address is decreased by 1. * CGRAM operates the same as DDRAM, when reading from or writing to CGRAM.

SH: Shift of Entire Display

When DDRAM read (CGRAM read/write) operation or SH = "0", shift of entire display is not performed. If SH = "1" and DDRAM write operation, shift of entire display is performed according to I/D value (I/D = "1" : shift left, I/D = "0" : shift right).

4) Display ON / OFF Control

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

0 0 0 0 0 0 1 D C B

Control display/cursor/blink ON/OFF 1 bit register.

D : Display ON/OFF Control Bit

When D = "1", entire display is turned on. When D = "0", display is turned off, but display data remained in DDRAM.

C : Cursor ON/OFF Control Bit

When C = "1", cursor is turned on. When C = "0", cursor is disappeared in current display, but I/D register remains its data.

B : Cursor Blink ON/OFF Control Bit

When B = "1", cursor blink is on, which performs alternate between all the "1" data and display character at the cursor position. When B = "0", blink is off.

80 SEG / 16 COM DRIVER & CONTROLLER FOR DOT MATRIX LCD S6A0070

5) Cursor or Display Shift

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

0 0 0 0 0 1 S/C R/L x x

Without waiting or reading the display data, shift right/left cursor position or display. This instruction is used to correct or search display data. (Refer to table 4) 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 displayed data is shifted repeatedly, each line is shifted individually. When display shift is performed, the contents of the address counter are not changed.

Table 4. 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 x x

DL : Interface data length control bit

When DL = "1", it means 8-bit bus mode with MPU. When DL = "0", it means 4-bit bus mode with MPU. So to speak, DL is a signal to select 8-bit or 4-bit bus mode. When 4-bit bus mode, it needs to transfer 4-bit data in two times.

N : Display line number control bit

When N = "0", it means 1-line display mode. When N = "1", 2-line display mode is set.

F : Display font type control bit

When F = "0", 5 × 7 dots format display mode When F = "1", 5 × 10 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. This instruction makes CGRAM data available from MPU.

S6A0070 80 SEG / 16 COM DRIVER & CONTROLLER FOR DOT MATRIX LCD

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 from MPU. When 1-line display mode (N = 0), DDRAM address is from "00H" to "4FH". In 2-line display mode (N = 1), DDRAM address in the 1st line is from "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 0 BF AC6 AC5 AC4 AC3 AC2 AC1 AC0

This instruction shows whether S6A0070 is in internal operation or not. If the resultant BF is "1", it means the internal operation is in progress and you have to wait until BF to be Low, and then the next instruction can be performed. In this instruction you can read also the value of 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

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 R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

1 1 D7 D6 D5 D4 D3 D2 D1 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 is read first is invalid, because the direction of AC is not determined. If you read RAM data several times without RAM address set instruction before read operation, you can get correct RAM data from the second, but the first data would be incorrect, because 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 read operation, display shift may not be executed correctly.

NOTE: In case of RAM write operation, after this AC is increased/decreased by 1 like read operation. In this time,

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

2) Interface with 4-bit MPU

When interfacing data length is 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 two parts. Busy Flag outputs "1" after the second transfer are ended. Example of timing sequence is shown below.
