3 ********超高性价比的51单片机--20元以下的可达72K程序空间及可在任何地址存储数据的增强性51单片机************
4 ************采用超级FLASH存储器的超级51单片机---SST89E/V52-54-58-516RD,具有超级程序和数据空间的功能******

11 1.片内的用户程序容量超过标准51单片机的极限--64K,单片最大可达72K的用户程序空间
12 2.片内FLASH的任意地址均可作为数据或程序单元进行存储,具有超级的灵活性,这是其它51单片机所不能达到的极限.
13
14 本例子,就简单说明了这些功能的实现:
15 1.在SST89E516RD/564RD的BLOCK0(64K)内存放BLOCK0.C的程序文件,允许最大到64K;在BLOCK1(8K)内存放BLOCK1.C的
16 程序文件,最大到8K,通过KEIL C51的BANK分区指令,可有效将两个BLOCK的程序合在一起,互相调用,从而形成64+8=72K
17 的程序容量空间.
18 2.在两个BLOCK内都存放有FLASH的擦写指令,便可对72K内的任意非程序空间的剩余空间都作为DATA存储空间来用,从而
19 打破了在MCU片内最大只能64K数据空间的限制,数据存储片内也可超过64K.
20 3.本示例采用最精简的函数和结构,主在说明在SST89E516/564RD的单片机内可实现超过64K的程序空间和任意地址存储数
-据
21 的功能.
