<Accordingly, the Court construes the term to mean “a ring oscillator variable speed system clock that is located entirely on the same semiconductor substrate as the CPU and does not directly rely on a command input control signal or an external crystal/clock generator to generate a clock signal.”>

Could someone pls clarify why it is worded in this way "not directly" assuming then that indirect is OK. My belief is that this would allow refinements from an off chip clock generator, but I really do not have a clue. Help! Opty
