问题描述：
将下列英文翻译成中文,请英语过硬者来!谢绝翻译软件直译!
The P89C668 device contains a non-volatile 64KB Flash program memory that is both parallel programmable and serial In-System and In-Application Programmable. In-System Programming (ISP) allows the user to download new code while the microcontroller sits in the application.
In-Application Programming (IAP) means that the microcontroller fetches new program code and reprograms itself while in the system. This allows for remote programming over a modem link. A default serial loader (boot loader) program in ROM allows serial In-System Programming of the Flash memory via the UART without the need for a loader in the Flash code. For In-Application Programming, the user program erases and reprograms the Flash memory by use of standard routines contained in ROM.
1L辛苦了,但是翻译软件翻得吧, "非挥发性"是什么意思?而且全篇语言很不通顺!
