Busy:
When high, the NT7501 is busy due to either internal operation or being reset. Any command is rejected until
BUSY goes low. The busy check is not required if enough time is provided for each cycle.
Indicates the relationship between RAM column address and segment drivers. When low, the display is
reversed and the column address “100-n” corresponds to segment driver n. When high, the display is normal
and column address corresponds to segment driver n.
Indicates whether the display is on or off. When it goes low the display turns on. When it goes high, the
display turns off. This is the opposite of Display ON/OFF command
Indicates that initialization is in progress due to RES signal or by reset command. When low, the display is
on. When high, the chip is being reset.

ON/OFF:
RESET:
6. Write Display Data
Write 8-bit data in the display RAM. As the column address is incremented by 1 automatically after each writing, the
microprocessor can continue to write data of multiple words.

7. Read Display Data
Reads 8-bit data from the display RAM area specified by the column address and page address. As the column address is
incremented by 1 automatically after each reading, the microprocessor can continue to read data of multiple words. A
single dummy reading is required immediately after the column address setup. Refer to the display RAM section of
FUNCTIONAL DESCRIPTION for details. Note that no display data can be read via the serial interface.

8. ADC Select
Changes the relationship between the RAM column address and the segment driver. The order of the segment driver
output pads can be reversed by the software. This allows flexible IC layout during the LCD module assembly. For details,
refer to the column address section of Figure4. When display data is written or read, the column address is incremented by
1 as shown in Figure4.
