: Don’t Care
S/C = “0”, R/L = “0”
This instruction shifts left the cursor and blink positions by 1 (decrements the
content of the ADC by 1).
This instruction shifts right the cursor and blink positions by 1 (increments the
content of the ADC by 1).
This instruction shifts left the entire display by 1 character position. The cursor
and blink positions move to the left together with the entire display.
The Arbitrator display is not shifted.
(The content of the ADC remains unchanged.)
This instruction shifts right the entire display by 1 character position. The cursor
and blink positions move to the right together with the entire display.
The Arbitrator display is not shifted.
(The content of the ADC remains unchanged.)
S/C = “0”, R/L = “1”
S/C = “1”, R/L = “0”
S/C = “1”, R/L = “1”
In the 2-line mode, the cursor or blink moves from the first line to the second line when the cursor at digit 40
(27; hex) of the first line is shifted right.
When the entire display is shifted, the character pattern, cursor or blink will not move between the lines (from
line 1 to line 2 or vice versa).
6) Function Setting

The execution time of this instruction is 37
μ

Instruction code:
(1) When the “DL” bit (DB
4
) of this instruction is “1”, the data transfer to and from the CPU is performed
once by the use of 8 bits DB
7
to DB
0
.
When the “DL” bit (DB
4
) of this instruction is “0”, the data transfer to and from the CPU is performed
twice by the use of 4 bits DB
7
to DB
4
.
(2) The 2-line display mode is selected when the “N” bit (DB
3
) of this instruction is “1”. The 1-line display
mode is selected when the “N” bit is “0”.
The arbitrator is displayed when the “ABE” bit (DB
2
) of this instruction is “1”.
The arbitrator is not displayed when the “ABE” bit (DB
2
) of this instruction is “0”.
(3) The transfer direction of the segment signal output data is controlled.
When the “SSR” bit (DB
1
) of this instruction is “1”, the data is transferred from
SEG
100
to SEG
1
.
When the “SSR” bit (DB
1
) of this instruction is “0”, the data is transferred from
SEG
1
to SEG
100
.
The transfer direction of the common signal output data is controlled.
At 1/n duty,
When the “CSR” bit (DB
0
) of this instruction is “1”, the data is transferred from
COMn to COM1
.
When the “CSR” bit (DB
0
) of this instruction is “0”, the data is transferred from
COM1 to COMn
.
After the ML9042 is powered on, this function setting should be carried out before execution of any
instruction except the Busy Flag Read. After this function setting, no instructions other than the DL Set
instruction can be executed. In the Serial I/F Mode, DL setting is ignored.
