Introduction
This document describes methods to create an accurate real time clock (RTC) using the 71M653x-family Teridian
Energy Meter ICs. The sample code discussed is from the released Demo Code for the 71M6533, but similar
techniques may be used with the 71M6531, 71M6532, or 71M6534 Teridian Meter products.
Theory of Operation
There are two basic ways to make the RTC accurate:
Correct the RT……
