Filed: 1985-11-22
Abstract: PURPOSE:To omit a back-up power supply, by transfer-memorizing operational states and memories in a central operational processing unit to a nonvolatile memory when abnormal voltage is detected in a power voltage detection circuit which is installed on a similar chip of a one-chip microcomputer.
