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).

When
tha crystal oscillation for timer operates, the standby supply current

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!.

Standby
I/O
leakage
current
is
the leakage current of I/O pins
in
the "Halt" and "Disable" state.
