Abstract

Clock regulation apparatus for preventing a logic switching mechanism from operating incorrectly. The apparatus has a supply voltage input that receives a supply voltage, which is also applied to the logic switching mechanism, a comparison unit that outputs an error signal if the supply voltage value drops below a reference value, a clock signal input that receives a clock signal from a clock generator, and a clock suppression unit, which is coupled to the clock signal input and to the comparison unit, that has a clock output for outputting the clock signal and that suppresses or delays the clock signal for a duration of at least one clock period if the error signal exists.
