Patent Number: 8,819,401

Title: Semiconductor device and reset control method in semiconductor device

Abstract: Reset request from external are held at a reset request holding unit having holding units connected in series; a reset switching unit performs a logical product operation of all of outputs of the holding units to set it as an asynchronous reset request, setting an output of the holding unit at a final stage of the holding units as a synchronous reset request, performing a logical product operation of the asynchronous reset request and the synchronous reset request, and outputs an operation result; the asynchronous reset request is masked in a synchronous reset mode; and a reset signal is output from a reset output unit based on the operation result at the reset switching unit.
