RTC补偿

资料介绍
摘要:本应用笔记介绍了创建一个准确的实时时钟(RTC) ,使用Teridian公司的71M6533 ,第三代,多相能源米上系统芯片( SoC)的方法。类似的技术,可用于与71M6531 , 71M6534 ,和其他Teridian公司的能源米集成电路。有两种基本方法,以使RTC的准确:正确的RTC所有预期的错误,或从行频RTC 。无论使用哪种方法, RTC运行在停电期间的调整精度高。

RTC Compensation
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
