Using 3.3V or 5V Supply and connecting Vcc1, Vcc2, BSLPY and BCTRL

Notes: BCTRL regulates the device current, thus R1 and R2 should have

good tolerance rating. If available, a voltage regulator is the preferred

method of bias.

In this example we set R2 at 10MOhm and solve for R1 with simple voltage

divider equation. Use high resistance values to limit leakage current.
