    摘要: A data processing system includes a power control circuit, a processor, a power supply, and a plurality of other components. Upon system reset, the power control circuit can generate at least one sequencing signal indicating a first sequence in which power is to be supplied to the plurality of components. Similarly, power sequencing code executed by the processor upon system reset can selectively generate at least one sequencing signal indicating a second sequence in which power is to be supplied to the plurality of components. The power supply, which can receive both the sequencing signal generated by the power control circuit and the sequencing signal generated by the power sequencing code, supplies power to the plurality of components in the second sequence if the power supply receives the sequencing signal generated by the power sequencing code. In one embodiment, the plurality of components require a plurality of different power supply voltages.
