Enable Bus-Hold Circuitry logic option

A logic option that enables bus-hold circuitry during device operation. If this option is turned on, a pin retains its last logic level when it is not driven, and does not go to a high impedance logic level. The Enable Bus-Hold Circuitry option should not be used at the same time as the Weak Pull-Up Resistor option.

This option is ignored if it is applied to anything other than a pin.
