Abstract
An apparatus for selecting a clock source in a microprocessor. The apparatus receives a first clock and a second clock. The apparatus has a clock select unit capable of detecting the first clock and selecting between the first clock and the second clock without an external selection signal indicating which clock is to be selected. If the clock selection unit detects the first clock, then the first clock is selected. Otherwise, if the first clock is not detected, then the second clock is selected. The clock selection unit provides an output clock based on the selection.
