After reset is canceled, the capacity of C
until INT terminal first falls.
After reset is canceled, the capacity of CH is charged rapidly
until INT terminal first rises and falls.
After reset is canceled, holds the stationary light while HOLD
terminal is HIGH.
After reset is canceled, as HOLD terminal is HIGH and INT
terminal is HIGH, the first integration is implemented while INT
terminal is HIGH. Therefore,the first integration must be
finished(INT terminal from HIGH to LOW) until stationary light
hold will be completed (HOLD terminal from HIGH to LOW)
After reset is canceled, the second integration is implemented as
HOLD terminal is LOW and INT terminal is HIGH. And,the
second integration is completed by exceeding judgement level of
CINT terminal although INT terminal is HIGH.
These terminals implement the following controls by inputting
HIGH/LOW.

Stationary light hold
When the second integration starts,This terminal becomes from
HIGH to LOW. If CINT terminal exceeds judge level or INT
terminal becomes from HIGH to LOW, this terminal becomes
from LOW to HIGH.
IRED ON/OFF is required except for above mentioned
control signals. But applying the timing of HOLD is
available.
