Abstract
An input to the control unit of a microprocessor places the microprocessor in a WAIT condition whenever the input clock frequency is determined to be less than a predetermined minimum value. A timing circuit which includes a relatively high capacitance device generates a 'kill' signal whenever the time interval between successive clock pulses is greater than a value corresponding to a cut-off frequency. The kill signal is applied to the control unit of the microprocessor and cannot be reset except with a system reset.
