Abstract
An interface controller adaptively changes the data transfer rate of data being transferred between two or more devices depending on whether one of the devices is powered by an internal power supply and on the destination of the data. The controller includes a clock generator that generates a clock signal, a transfer unit that performs one of a first data transfer and a second data transfer at a transfer rate based on the clock signal, and a control circuit for adaptively changing the frequency of the clock signal depending on whether the first or second data transfer is to be performed.
