The EN and MODE pins have an active 800-kΩ pulldown resistor to ground. When the EN and MODE pins are logic high, there is high impedance to make sure there is no high leakage current in these pins. When the EN and MODE pins are logic low or floating, there is a 800-kΩ pulldown resistor to make sure the EN and MODE pins cannot be coupled to the logic high by the noise. TI suggests the pulling high capability be stronger than the 800-kΩ pulldown resistor when enabling the TPS61094.
