Frequency characteristics revision pin. By installing
a capacitor between this pin and GND, close-loop

Index input pin.
When the I+ pin is at an low level, I1 operates with
the fixed current of I1=10
μA and when at an high
level, I1 does not flow.
Hysteresis width is determined by the resistor
attached externally to the I+ pin.
