INOTEI 1. Applied to PMOS load of CMOS output pins and CMOS I/O common pins among
0
and R terminals.
2. Applied to CMOS output pins, CMOS I/O common pins, input pins with pull up MOS, and I/O common pins with pull up MOS
among
0
and R terminals.
3. Applied to open<irain output pins and open<irain I/O common pins among 0 and R terminals.
4.
Pull up MOS currant is axcluded.
5.
Applied to the supply current when the LCD-III is in the reset state and the crystal oscillation for timer doesn't operate
ICurrent that flows in the input/ouljut circuit and in the power supply circuit for LCD is excluded).

Note

When tha crystal oscillation for timer operates, the standby supply current 121 IcCS2 flows in addition to Icc.
When the LCD-III is installed in the user's system, and in operation current increases according to the external circuitry and devices.
Those are connected to the LCD-III. User should design the power supply in consideration of this point IThe difference between
the measured current in the above reset stata and that measured in the operatio.nal state in tha user's system is the increased part of
the supply current!.
6. Standby I/O leakage current is the leakage current of I/O pins in the "Halt" and "Disable" state.
