Abstract
A semiconductor device containing a CPU capable of receiving an interrupt request signal and a task control circuit is provided. The semiconductor device includes a CPU (processor), a save circuit, and a task control circuit. The CPU includes a program counter that is updated when a task is executed. The semiconductor device includes an interrupt-related data save circuit that stores the data of the program counter when the CPU receives a CPU interrupt request signal. The data of the program counter stored in the interrupt-related data save circuit is stored in an save circuit and is used for restoring from the interrupt processing.
