3 Overview

The implementation described in this document supports both Single-Unit and Ping-Pong EEPROM Emulation. Single-Unit and Ping-Pong implementations both support two modes, Page-Programming and 64-Bit Programming mode. Ping-Pong Emulation will be described first, and Single-Unit will be described subsequently.

There are multiple user-configurable EEPROM variables supported by this implementation. These variables are detailed in Section 5.1.
