Abstract
According to an embodiment, a semiconductor device can be in an operating state and a standby state with a choice of a plurality of standby state levels and has a CPU, an interrupt control circuit, and a hardware control circuit. The CPU makes a comparison of a first return time period corresponding to a first standby state level that is a shallowest one selected from among allowable standby state levels set for one or more tasks executed immediately before transition to the standby state with a second return time period selected from among allowable return time periods set for the one or more tasks executed, changes a standby state level of the standby state if the first return time period is judged to be longer than the second return time period as a result of the comparison, and controls the hardware control circuit.
