BUSY When BUSY=1, indicates an internal operation being done or reset.
The command cannot be accepted until BUSY=0 is reached. However, if the cycle time is
satisfied, the command needs not be checked.
ADC Indicates the correspondence relationship between the column address and segment driver.
0: Reversal (column address 199–n ↔ SEG n)
1: Normal rotation (column address n ↔ SEG n)
(Reverses the polarity of ADC command.)
ON/OFF ON/OFF: Specifies display ON/OFF
0: Display ON
1: Display OFF
(Reverses the polarity of display ON/OFF command.)
RESET Indicates the RES signal or that initial setting is being done using the reset command.
0: Operating state
1: Resetting
(6) Display Data Write
This command writes 8-bit data to the specified address of the display data RAM. Since the column address is
automatically incremented by 1 after the data is written, the MPU can successively write the display data.

(7) Display Data Read
This command reads the 8-bit data in the specified address of the display data RAM. Since the column address is
automatically incremented by 1 after the data is written, the MPU can successively read the data consisting of multiple
words.
Besides, immediately after the column address is set, dummy read is required one time. For details, see the description
of the Display data RAM and internal register access of "Function Description".
When using the serial interface, the display cannot be read.

(8) ADC Select (Segment Driver Direction Select)
This command can reverse the correspondence relationship between the column address of the display RAM data shown
in Figure 4 and the segment driver output. Therefore the order of the segment driver output pin can be reversed using
the command. After the display data is written and read, the column address is incremented by 1 according to the column
address of Figure 4. For details, see the Column address circuit of "Function Description".
