Command Sequence when Built-in Power Supply is Turned OFF
To turn off the built-in power supply, follow the command sequence as shown below after setting the system to standby mode.
Static Indicator ON
Display OFF
Entire Display ON
Command ADH
Command AEH
Command A5H

}
Power Save
Command
Reset Circuit
When the RES input goes low, this LSI is initialized.
Initialized status
1. Display OFF
2. Normal display
3. ADC select: Normal display (ADC command D0 = low)
4. Read modify write OFF
5. Power control register (D2, D1, D0) = (0, 0, 0,)
6. Register data clear in serial interface
7. LCD power supply bias ratio 1/6
8. Static indicator: OFF
9. Display start line register set at line 1
10. Column address counter set at address0
11. Page address register set at page 0
12. Output status register (D3) = (0)
13. Electronic control register set at 0
14. Test command OFF
As seen in Figure 8 Microprocessor Interface (Reference Example). Connect the RES pad to the reset pin of the
microprocessor and initialize the microprocessor at the same time.
In case the NT7501 does not use the internal LCD power supply circuit, the RES must be low when the external LCD power
supply is turned on.
When RES goes low, each register is cleared and set to the above initialized status. However, it has no effect on the oscillator
circuit and output pads (FR, CL, DYO, D0 to D7)
The initialization by RES pad signal is always required during power-on. If the control signal from the MPU is HZ, an
overcurrent may flow through the IC. A protection is required to prevent the HZ signal at the input pads during power-on.
Be sure to initialize it by RES pad when turning on the power supply. When the reset command is used, only parameters 8 to
14 in the above initialization are executed.
