LV5230LG - Dot-matrix LED Driver
Equivalent Circuit SVCC A1 pin A2 RT Reference current setting resistor connection pin.
By connecting the external resistor between this pin and GND, the reference current is generated.
The pin voltage is about 0.61V.
Change of this current value enables change of the oscillation frequency and
