(NOTE) 1. Applied to PMOS load of CMOS output pins and CMOS I/O common pins among D 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 D and R terminals.
3. Applied to open-drain output pins and open-drain I/O common pins among 0 and R terminals.
4. Pull up MOS current is excluded.
5. Applied to the supply current when the LCD·IV is in the reset state and the crystal oscillation for timer doesn't operate.
(Current that flows in the input/output circuit and in the power supply circuit for LCD·is
exclud~d).

When the crystal oscillation for timer operates, the standby supply current (2) leeS2 flows in addition to Icel or Ice2.
When the LCD·IV 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·IV. User should design the power supply in consideration of this point (The
difference between the measured current in the above reset state and that measured in the operational state in the 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.

Current that flows in the input/output circuit and in the power supply circuit for LCD is excluded. The standby supply

(only the crystal oscillator for timer, 5·bit divider and 6-bit prescaler are in operation).
