Input to the internal voltage regulator.
Digital supply voltage. Normally connected to VREG.
Output from the internal voltage regulator.
CF1P/CF1N/CF2P/CF2N are the connection pins for connecting external fly capacitors to the
step-up regulator.
Internal Voltage Reference for external decoupling.
Ground for decoupling of Internal Voltage Reference. Do not connect to GND or SGND on PCB.
