电力测量芯片ATT7022b的应用笔记，值得参考(Power Measurement Chip ATT7022b application notes, reference should be)

用于实现单片机16F648A和微控制器的通信。通过回车来确定通信是否成功，成功了可以从对应的LED开关看出，同时电脑终端会出现正确或错误的回复(This program is designed to convert 16F648A into a working micro-controller system which waits for one of a number of Carriage Return terminated messages and turn on or turn off one of four LEDs corresponding to the message. If the message is decoded successfully, an OK will be sent to the PC, otherwise an Error message will be returned )

该文档为IRMCF3xx的中文参考手册，对于使用这颗芯片的人来讲，这个资料非常珍贵。(The documentation for the IRMCF3xx the Chinese reference manual for the use of the chip of the people, this information is very valuable.)
