Real Time Clock Compensation
摘要 :The Teridian 71M6521, a polyphase residential energy-meter system-on-chip (SoC), has a real-time clock (RTC) that requires compensation to achieve high metering accuracy. This application note describes how to use software to compensate the 71M6521's RTC. Similar principles may be used with the 71M6511, 71M6513, and other Teridian energy-meter ICs.
