利用单片机外围接口芯片PSD934FZ中包含的8块32KByte主闪速存储器（MainFlash memory）和4块8KByte第二闪速存储器（Secondary Flash memory）,通过对程序存储空间采用分页的办法,让CPU轮流工作在两页程序上,使得80C196KC单片机程序可以在大于64KB的空间上运行。在不增加硬件开销的情况下实现程序空间的扩充。
By using eight 32KByte main flash memories and four 8KByte secondary flash memories included in the peripheral interface chip PSD934FZ of the one-chip computer, the program memory is arranged in a paged manner to make the CPU work in turn Two-page program, making 80C196KC microcontroller program can run in more than 64KB of space. Program space expansion without additional hardware overhead.
