Abstract
Circuitry for driving a pin of a device includes a first circuit path terminating in a first impedance, a second circuit path terminating in a second impedance, where the second impedance is less than the first impedance, and a selection circuit to control operation of the second circuit path. When the second circuit path is not configured for operation, the first circuit path is configured to output one of plural first voltage signals. When the second circuit path is in configured for operation, the second circuit path is configured to output a second voltage signal. The second voltage signal is greater than the plural first voltage signals.
