More Information
Summary:An inventive information processor performs a predetermined process substantially continuously without causing runaway in its CPU even if extraneous noise has entered the power supply terminal thereof. When the incoming noise reaches relatively low Level 1(L), important information, determining the state of the CPU, is protected by saving it on a register. Thereafter, when the noise level exceeds Level 1(H), important information, representing the status of the predetermined process, is protected by storing it on a memory. Subsequently, when the noise level reaches Level 2, the CPU is suspended. And when the noise has decreased to less than Level 1(L), the predetermined process is resumed in accordance with the information saved and protected on the register and memory. Accordingly, even if noise has entered, the predetermined process can be continued without causing runway in the CPU after having been suspended for a while.
