1. A method for providing bi-directional communication capability between a first device and a second device, comprising:

  • determining, by the first device, that a first signal line is in a deasserted state;

    based on the first device determining that the first signal line is in the deasserted state, driving, by the first device, the first signal line to an asserted state;

    subsequent to the first device driving the first signal line to the asserted state, ceasing the driving of the first signal line by the first device;

    subsequent to the first device ceasing the driving of the first signal line, determining, by the first device, that the first signal line is in the asserted state; and

    based on the first device determining that the first signal line is in the asserted state, initiating a transfer of data from the first device to the second device.
