FM1808是一种掉电可保存的RAM存储器,应用很广泛.

学习用，使用前，认真阅读，按实际情况更改IO口！-to study, use, read carefully, according to the actual situation changes IO mouth!

使用的同步串行三线SPI 接口，可以方便的连接采用SPI 通信协议的外围或另一片AVR 单片机，实现在 短距离内的高速同步通信。ATmega128 的SPI 采用硬件方式实现面向字节的全双工3 线同步通信，支持主 机、从机和2 种不同极性的SPI 时序，通信速率有7 种选择，主机方式的最高速率为1/2 系统时钟，从机方式 最高速率为1/4 系统时钟。-Use three-wire SPI synchronous serial interface, can be used to facilitate the connection of the external SPI communication protocol or another chip AVR microcontroller, realize in the short distance high-speed synchronous communication. ATmega128
