应用背景Logical separation of program and data memory All 8051 devices have specific memory organization, they have separate address spaces for Program (ROM) and Data (RAM) Memory. This logical separation of Memory is useful because it allows the Data Memory to be accessed by 8-bit addresses, which can obviously be more quickly stored and manipulated by an 8-bit CPU. Of course, the l6-bit Data Memory addresses can still be generated with the DPTR register. Program Memory Program Memory can only be read, not written to. The address space for 8051 core is 16- bit, so there is maximum of 64K bytes of Program Memory. Up to 4 Kbytes of Program Memory can be on chip, internal Program Memory of the 8051 core. For access to external Program Memory is used signal PSEN (Program Store Enable). Data Memory Data Memory is on a separate address space than Program Memory. For external Data Memo

应用背景主要应用于51单片机的SD卡操作，完美适用于STC12c60s2单片机，现在的这方面的资源比较少，适用于51的更少，所以如果有需要这方面的资源，可以参考下，个人觉得很不错，已调通。关键技术51单片机的SD卡操作，完美适用于STC12c60s2单片机，函数有点大，住要是ZNFAT.C文件，里面是文件系统的主要函数，不过有些函数还未有待实验，SD.H文件的4个引脚可以根据自己的单片机自己定义，串口函数波特率为2400；
