Abstract
A clock switch controller has a clock status register which stores current clock data which identifies which of two or more clock signal sources is a current clock signal source currently in use as a system clock signal source. State machine logic of the controller automatically switches, in response to a clock switch signal, the system clock signal source from the current clock signal source to a new clock signal source of the two or more clock signal sources.
