  • Method and apparatus for controlling writing of flash EEPROM by microcomputer
    Patent number: 6567930
    Abstract: An apparatus that make it possible for a microcomputer to execute self-programming without the occurrence of shutdown or initialization (restart) includes a flash EEPROM for storing programs and data, a monitoring circuit for monitoring program runaway and malfunction, and the microcomputer. When rewriting of the content of said flash EEPROM (i.e., self-programming) is executed via control by the microcomputer, the monitoring circuit controls output/suppression of an abnormality detection signal on the basis of an externally entered flash EEPROM write-enable signal and a monitoring-circuit operation-control signal output from the microcomputer.
