In this document, Maxim tackles two firmware improvements that were applied to the Demo Code version 4.8p for Maxim's Teridian 71M6521 family of energy meter ICs. These improvements make transitions between power modes on the 71M6521 more reliable and support proper correction of the real-time clock (RTC) after return to mission mode. This document isolates the changes and describes details so that the updates can be retrofitted into customer firmware, if needed.
