NOTES:
1. Set VDD above the start threshold before setting at 9V.
2. Does not include current of the external oscillator network.
3. Ensured by design. Not 100% tested in production.
4. The pullup / pulldown circuits of the driver are bipolar and MOSFET transistors in parallel. The output resisstance is the RDS(ON)
of the MOSFET transistor when the voltage of the driver output is less than the saturation voltage of the bipolar transistor.
