P89V51RD2系列芯片是具有串口下载功能（ISP）和在KEIL中进行调试的功能（SOFTICE）。 新的芯片是ISP功能，通过FlashMagic 软件可以设置其为SOFTICE功能。 但要想回到ISP功能，则没有现成的好办法，只有通过编程器了。 但现在可以通过这个程序来恢复其ISP功能（禁止SOFTICE）。-P89V51RD2 series with the serial port chip is the ability to download (ISP) and the KEIL for debugging feature (SOFTICE). The new chip is the ISP, through FlashMagic software can be set to SOFTICE its function. However, to return to the ISP, there is no ready-made good, and that only through a programmer. But now through this procedure to restore its ISP (Prohibition SOFTICE).
