Claim Text:
1. A semiconductor device comprising: a regulator unit for generating an internal power supply voltage based on a power supply voltage supplied from outside the semiconductor device; an internal circuit which operates on the internal power supply voltage; a current detection unit for monitoring a power supply current supplied to the internal circuit; and a control unit for controlling operation of the internal circuit, wherein the internal circuit comprises a data processing unit for executing a program, wherein when the current detection unit detects that the power supply current exceeds a predetermined threshold value, the current detection unit outputs a detection result indicating that, wherein the control unit restricts the operation of the internal circuit in accordance with the detection result, wherein the regulator unit comprises wherein the current detection unit comprises wherein the semiconductor device futher comprises a register unit which can be accessed by the data processing unit and in which control information is set, and wherein the determination unit changes the predetermined threshold value in accordance with the control information set in the register unit.
