Having a system that regularly writes parameters to the EEPROM can wear out the
EEPROM, since it is only guaranteed to endure 100 k erase/write cycles. Writing the
parameters to a circular buffer in EEPROM where each of the elements in the buffer
can endure 100 k erase/write cycles can circumvent this. However, if the system is
exposed to RESET conditions, such as power failures, the system needs to be able to
identify the correct position in the circular buffer again. This document describes how
to make safe high endurance parameter storage in EEPROM.
