A memory controller and method thereof configures a prefetch buffer dynamically for interfacing between multiple bus masters of different burst support and multiple memories having different characteristics. The yaw drive device of the yaw system, which revolves a nacelle depending on the wind direction, includes a electric motor which is fixedly provided on a nacelle base plate, with an output shaft substantially aligned with a pivot of the nacelle. In one embodiment, a method of processing defect conditions in a maintenance endpoint of a first domain, the MEP a component of a bidirectional forwarding detection to Y. The circuit may further include metallization adapted to connect the well and annular region to opposite polarities of a power supply voltage, or in some embodiments to preclude such connection.
