Abstract
A system includes a serial bus , at least a first portion of which is formed on a circuit board. A first physical layer controller is coupled to the first portion of serial bus . This physical layer controller includes a register set with a plurality of eight-bit registers addressable by four-bit addresses. In this device, at least one of the seventh or eighth bits of the 0010 register is permanently programmed with a logical “1”. This physical layer controller is also backward compatible with a physical layer controller that conforms with IEEE-Std-1394-1995. The system also includes another physical layer controller , which may or may not be the same as physical layer controller , link layer controllers and and at least one processor (or controller)
