扩展Intel Hex的格式(最大1M): 由于普通的Intel的Hex记录文件只能记录64K的地址范围,所以大于64K的地址数据要靠扩展Intel Hex格式的文件来记录.对于扩展形式Hex文件,在每一个64K段的开始加上扩展的段地址规定,下面的数据地址均在这个段内,除非出现新的段地址定义. The Intel HEX file is an ASCII text file with lines of text that follow theIntel HEX file format. Each line in an Intel HEX file contains one HEX record.These records are made up of hexadecimal numbers that represent machinelanguage code and/or constant data. Intel HEX files are often used to transferthe program and data that would be stored in a ROM or EPROM. Most EPROMprogrammers or emulators can use Intel HEX files.
