Rev. 1.1a
• Stand-by State
This command stops the operation of the duty LCD display system and operates only the static drive system for
indicators. Consequently the minimum current consumption required for the static drive is obtained. The internal state
in the stand-by state is as follows:
(1) The LCD power supply circuit is stopped. The oscillator circuit is operated.
(2) The duty drive system liquid crystal drive circuit is stopped and the segment and common drivers output the V
(21) Power Save Reset
This command resets the power save state and returns the state before power save activation.
(22) n-Line Reversal Drive Register Set
This command sets the number of reversal lines of the liquid crystal drive in the register. 2 to 16 lines can be set. For
details, see the Display Timing Generator Circuit of “Function Description”.
(23) n-Line Reversal Drive Reset
This command resets the n-line reversal alternating current drive and returns to the normal 2-frame reversal alternating
current drive system. The value of the n-line reversal alternating current drive register is not changed.
(24) Built-in Oscillator Circuit ON
This command starts the operation of the built-in CR oscillator circuit. This command is valid only for the master
operation (M/S=HIGH) and built-in oscillator circuit valid (CLS=HIGH).

should be stopped at power save activation. For example, when providing each level of the liquid crystal drive
voltage using a stand-alone split resistor circuit, it is recommended that the circuit which cuts off the current
applied to the split resistor circuit should be added at power save activation. The S1D15710 series has the liquid
crystal display blanking control pin DOF and is set to LOW at power save activation. The function of the
external power supply circuit can be stopped using the DOF output.
