Name and Functions
⎯
LCD step-up circuit
capacitance connection
pins (H8/3857 Group
only): These pins connect
external capacitances for
LCD step-up. Connect
capacitances according to
the step-up factor.
I/O
LCD drive power supply
level (H8/3857 Group):
When the OPON bit is set
high, these bits output LCD
drive power supply levels V1
to V5. If the built-in op-amp
drive capacity is inadequate,
connect a capacitor to
provide stabilization. If
levels V1 to V5 are input
from an external source, set
the OPON bit low.
Input
LCD step-up circuit
reference power supply
(H8/3857 Group only): This
pin doubles as the LCD
step-up circuit reference
input voltage and step-up
circuit power supply, and
provides the LCD drive
voltage. Set 1.6 V ≤ V
V
. If the step-up circuit is
CC
not used, connect V
Output
LCD step-up voltage
output (H8/3857 Group
only): This is the LCD step-
up voltage output pin.
Connect a capacitance.
Input
LCD drive power supply
(H8/3857 Group only): This
is the LCD drive power
supply input pin. If the built-
in step-up circuit output
voltage is used for the LCD
drive power supply, short
this pin to VLOUT. Set V
≤ 7.0 V.
