Abstract
Clock signal control circuitry comprises a clock selector to output a current clock signal selected from two or more candidate clock signals and to execute a clock signal change operation to select a different one of the two or more candidate clock signals for output as the current clock signal; a counter to generate a count value by counting clock pulses of the current clock signal multiplied by a scaling value; and control logic to execute a scaling value change operation to change the scaling value in response to initiation of a clock signal change operation; in which the clock selector and the control logic are configured to cooperate to inhibit the output of the current clock signal during a scaling value change operation.
