pin/booster
capacitance
Potential difference between Vci and GND is boosted
twice or three times and then output. Magnitude of
boost is selected by instruction.
C1+, C1–

Booster
capacitance
External capacitance should be connected here when
using the double or triple booster.
C2+, C2–
8
Booster
capacitance
External capacitance should be connected here when
using the triple booster. Must be left disconnected
only when using the double booster.
RESET*

I
MPU or external
R-C circuit
Reset pin. Initializes the LSI when low.
Must reset after power-on.
OPOFF

I
V
CC
or GND
Turns the internal operational amplifier off when
OPOFF = V
, and turns it on when OPOFF = GND.
If the amplifier is turned off (OPOFF = V
), V1 to V5
must be supplied to the V1OUT to V5OUT pins.
VccDUM

O
Input pins
Outputs the internal V
level; shorting this pin sets
the adjacent input pin to the V
CC
level.
Outputs the internal GND level; shorting this pin sets
the adjacent input pin to the GND level.
