METHOD AND APPARATUS FOR DIFFERENTIAL STROBING IN A COMMUNICATIONS BUS

摘要

A method for ensuring proper strobe pre and post driving between a first data transfer and a second data transfer in a microprocessor system. The method includes generating a first strobe signal and a second strobe signal, pre-driving one of said first and second strobe signals before the first data transfer, post driving said pre-driven signal, determining which of said first and second strobe signals will be post driven, and pre-driving one of said first and second strobe signals before the second data transfer.
