(10) OVP
This is the over-voltage detection terminal.
An OVP terminal gains a voltage that is divided by resistances. It works with threshold voltage 2V.
It becomes the condition of the table at the time of the movement.

And once over-voltage protection works, it doesn't revert soon even if OVP is lower than 2V again.
It reverts after fixed time (the period of C_PWM) passes.
(11) SCP
CCFL electric current decrease by the CCFL opening and so on. And a charge begins in the condenser connected to
SCP when the voltage of DET_CR was less than 0.26V.
Latch is set when the voltage of the condenser is more than 2V. The voltage of each terminal at this time becomes a
table.
The charge of the condenser is stopped in the burst Duty again at the time of off period.
