ENABLE_BUS_HOLD_CIRCUITRY
Enables bus-hold circuitry during device operation. If this option is turned on, a pin will retain its last logic level when it is not driven, and will 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.
