Note 1: The external ROSC resistor adjusts oscillator bias current which sets the oscillator frequency. The oscillator frequency is not

available from the OSC pin.

Note 2: Control inputs can be driven even from low supply voltage controller due to low 0.9V VIH min threshold.

Note 3: DIN and CTRL pins have active pull-down by 400k

Ω which disabled to save current when inputs are pulled high.
