Abstract
A method for dynamically selecting a clock edge for recovering read data received from a slave at a master is provided that includes determining whether an internal clock signal is high when a first bit of read data is received at the master. One of a falling edge and a rising edge of the internal clock signal are selected for recovering the read data based on the determination of whether the internal clock signal is high when the first bit of read data is received at the master.
