Reset Circuit
When RES pin goes low,or when Reset command is
used,this LSI is initialized.
Initialized states :

• Serial interface internal shift register and counter
• Power saver mode is entered.
• Display normal
• Page address=0H
• Column address=00H
• Display start line address=00H
• Segment driver direction = normal
• Common driver direction = normal
• Read modify write OFF
• Power control register (D2, D1, D0) = (0, 0, 0)
This faculty is available only S1D15B01D00B
This faculty is not available by reset command, it is abailable only when hard reset : RES=LOW is active.

• Oscillation circuit is stopped.
• The LCD power supply circuit is stopped.
• Display OFF
• Display all points ON
• Segment/common driver outputs go to the V
level.

When reset is detected, this LSI is set to above initialized
states. However it has no effect on contents of DDRAM.
As seen in “Microprocessor Interface (Reference
Example)”, connect RES pin to the reset pin of the MPU
and initialize the MPU at the same time. The initialization
by RES pin is always required during power-on.
If the control signal from MPU is HZ, an overcurrent
may flow through the LSI. A protection is required to
prevent the HZ signal at the input pin during power-on.
In case the S1D15B01 series does not use the on-chip
LCD power supply circuit, RES pin must be HIGH
when the external LCD power supply is turned on.
