Abstract:
A method for controlling transmission of data from a sender to a receiver via a data bus to minimize digital inter-symbol interference, comprising the steps of:(A) executing a start data transfer command; (B) waiting for a FIFO register at the sender to be holding the data and determining when the FIFO register is holding the data; (C) driving the data held in the FIFO register onto the data bus; (D) pausing a first predetermined period of time for the data to be set up on the data bus; (E) asserting a REQ command associated with the data onto the data bus; and then (F) pausing a second predetermined period of time longer than the first predetermined period of time for the data to be sensed by data detection circuitry in the receiver, wherein pausing for the second predetermined period of time provides the data detection circuitry additional time to sense the data being transmitted on the data bus; wherein after step (C) and before step (D) the method further comprises the steps of: (G) inverting the data driven onto the data bus in step (C); (H) pausing a third predetermined period of time so that a quiescent negated voltage level is not reached on the data bus during subsequent steps of driving the data; and then (I) driving the data onto the data bus.
