Abstract
The semiconductor integrated circuit of this invention comprises at least one first semiconductor circuit (,) that is driven on the basis of on at least one first clock signal (,). In addition, there is at least one second semiconductor circuit (,) assisting the first semiconductor circuit (,), which operates on the basis of at least one second clock signal (,) independent of the first clock signal (,) and a request from the first semiconductor circuit (,). The second semiconductor circuit (,) comprises a halt means (,) that causes the second clock signal (,) to halt if necessary. This makes it possible to halt the second clock signal (,), thus halting the operation of the second semiconductor circuit (,).
