FAULT MODE RELEASE METHOD

摘要

PROBLEM TO BE SOLVED: To improve the operation speed and operability of an LSI by easily releasing the fault mode of the LSI. SOLUTION: A signal for recognizing data given to an internal register as set data to be set to the internal data is given to a control terminal for distinguishing whether data given to an input terminal is transfer data or the set data to be set to the internal register controlling operation in normal time to release a fault mode. A control terminal has a hazard removing function and when a system clock is stopped, the control terminal has the hazard function released and operated asynchronously.
