Precise stopping of a high speed microprocessor clock |
摘要 |
A method and means for selectively stopping the internal clock of a microprocessor on any of 16 phases using functional components which include: a clock multiplier circuit, that receives a clock signal input from an external oscillator or other appropriate source, and outputs the internal clock signal for the microprocessor; control logic circuitry for processing and inputting stop signals to the clock multiplier; and a clock special purpose register, which provides control signals to the control logic circuitry to determine when stopping of the internal clock signal should occur. |
