BI-DIRECTIONAL COMMUNICATION BETWEEN ELECTRONIC COMPONENTS

摘要

Embodiments are directed to a system comprising: a first device, and a second device coupled to the first device via an interface that provides a handshaking algorithm that ensures that only one of the first device and the second device initiates communication over the interface at a given point in time.

主权项

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.
