Abstract
A vehicle odometer system for counting pulses representing translation and storing in nonvolatile form binary data representing the decimal values of the odometer data. The architecture of the circuit is structured to use the data in the more significant digit positions of the odometer count as pointers for the nonvolatile storage addresses used to store data for the less significant digit positions. This arrangement ensures that the endurance capabilities of the nonvolatile memory array are taken into account while apportioning degradation in relation to the significance of the odometer data to be stored. Furthermore, electronic manipulation of the odometer data is prevented by inclusion of a write only high odometer value flag which cannot be removed and is redundantly detected.
