Column address set (Write)
This command specifies the column address of the display data RAM. The column address is specified by
successively writing the upper 4 bits and the lower 4 bits. Since the column address is automatically incremented
(by +1) every time the display data RAM is accessed, the MPU can read or write the display data continuously.
The incrementing of the column address is stopped at the address 7FH.

BUSY

BUSY
When BUSY is ‘1’, it indicates that the internal operations are being made or the LSI is being
reset. Although no command is accepted until BUSY becomes ‘0’, there is no need to check
this bit if the cycle time can be satisfied.
ADC
This bit indicates the relationship between the column address and the segment driver.
0: Reverse (SEG127
SEG0; column address 0H
7FH)
1: Forward (SEG0
SEG127; column address 0H
7FH)
(Opposite to the polarity of the ADC command.)
ON/OFF
This bit indicates the ON/OFF state of the display. (Opposite to the polarity of the display
ON/OFF command.)
0: Display ON
1: Display OFF
RESET
This bit indicates that the LSI is being reset due to the
RES
signal or the reset command.
0: Operating state
1: Being reset
Display data write (Write)
This command writes an 8-bit data at the specified address of the display data RAM. Since the column address is
automatically incremented (by +1) after writing the data, the MPU can write the display data to the display data
RAM continuously.
