  • Control device with rewriteable control data
    Publication number: 20050034034
    Abstract: A control device has a rewriteable flash memory for storing a program or data, and a CVN calculating unit for calculating a CVN value for guaranteeing the content of the flash memory. The control device also has a rewriteable EEPROM for storing a CVN calculation storage value. When it is determined that the flash memory was not rewritten, the CVN calculation storage value stored in the EEPROM is outputted before the CVN calculation is performed, and a calculation result is outputted. On the other hand, when the flash memory was rewritten, the calculation result is outputted after the CVN calculation is complete.
