ABSTRACT:
A microcontroller operating in synchronization with clock includes: an arithmetic unit operating in synchronization with the clock; an internal resource being connected to the arithmetic unit via a bus, and having at least a bus interface, and an internal circuit operating in synchronization with the clock; and a system resource prescaler which generates from the clock an operation permission signal denoting an operation permission state in m cycles out of n cycles of the clock (m=<n), and supplies the operation permission signal to the internal circuit of the internal resource. The above-mentioned internal circuit operates in synchronization with the clock when the operation permission signal denotes the operation permission state.
