ABSTRACT:
There is provided a reset circuit for reducing current consumption during resetting. A reset circuit20is constituted in such a manner that a pulse generation circuit22for generating a reset pulse signal (PRSTN)50from a reset signal input to an input terminal (RSTN) is connected to a plurality modules10, 12, 14, a register40arranged in the module10is initialized based on the reset pulse signal (PRSTN)50, a register42arranged in the module12of a next stage is initialized based on a module reset signal (MRSTN)60output from a control circuit30arranged in the module10of a previous stage, and a register44arranged in each of modules of stages thereafter, e.g., the module14, is initialized based on a module reset signal (MRSTN) output from a control circuit32arranged in the module12of a previous stage.
