NOTES :
1. Applied when D

impedance state.
2. Resistance when 0.5 V is applied between each output
pin and each power supply (V

). Applied
when power is supplied at power bias ratio of 1/9 in the
external power supply mode.
3. Current at the V
DD
pin when the master clock stops, the
chip is not selected (CSB = V
DD
), and no load is used.
All circuits stop.
4. Sleep mode supply current.
Stop internal oscillation clock, using external EXA signal.
Without using booster circuits. Graphic and segment
displays OFF. Icon display ON. No load.

5. Applied when no access is made by the MPU when the
internal oscillation circuit (R
F
= 680 k$) and power
supply circuit (PMODE = "L") are used. The electronic
volume is preset (the code is "1 1 1 1"). The display is
OFF and the LCD drive pin is not loaded.
