用于sst89x516(sst89x564)的Bootloader,使用超级终端用xmodem协议下载,(只支持bin文件的下载).在晶振为11.0592,未开双倍速的情况下,波特率为57600bps.在超级终端中长按 Z 键并对系统上电进入下载,否则500ms后跳转至block0中程序执行,可代替原SST中的BSL.可扩展实现远程升级-For sst89x516 (sst89x564) the Bootloader, use HyperTerminal to download using xmodem protocol, (only support bin file download). 11.0592 in the crystal to not open the case of double speed, baud rate is 57600bps. In the super-terminal long by ' Z'　button and enter the power system to download, otherwise jump to block0 after 500ms in the procedures can be alternative to the original SST in the BSL. scalability remote upgrade
