Integrated level shift and override circuit for a processor system |
摘要 |
An integrated circuit includes voltage identification (VID) logic and frequency identification logic (FID) for a CPU, as well as power good circuitry for indicating the suitability of electrical power supplies. A VID output signal to control a core voltage provided to the CPU is generated according to an input VID signal provided by the CPU, a sleep state signal, and a CPU mobility-type signal. FID, VID and power detection logic all level shift signals as required for external devices. A programmable table enables overriding of output FID and VID values.
