Control Pin Function
The control pin is used as configuration input to set parameters following a reset. The definition
of the pin changes immediately after a reset to its usual function. To set a configuration bit to 0,
attach a 100 k resistor from the pin to ground. No external circuitry is required to set a
configuration bit to 1.
