LINK/LOCATE RUN COMPLETE. 5 WARNING(S), 0 ERROR(S)
分析空间占用和其他也要解释Map 文件结构：
这个 Map 文件主要分为以下几个部分：
BL51 BANKED LINKER/LOCATER 版本信息：
显示了使用的 BL51 链接器/定位器的版本号。
BL51 BANKED LINKER/LOCATER V6.22.2.0 表明使用的是 Keil 的 BL51 链接器/定位器，版本号是 6.22.2.0。
链接器调用信息：
显示了 BL51 链接器被调用时使用的命令行参数，包括：
输入的目标文件 (.obj 文件)。
输出的 Map 文件名。
内存大小 (RAMSIZE (256)，表示 RAM 大小为 256 字节)。
MEMORY MODEL：
MEMORY MODEL: SMALL 表示使用了 SMALL 内存模型，这意味着代码和数据都在 64K 范围内。
INPUT MODULES INCLUDED：
列出了参与链接的所有输入模块 (.obj 文件)，包括：
您的源代码编译生成的目标文件 (main.obj, Timer0.obj, UART0.obj, OPTIONS_SN8F5702A.obj).
Keil 的 C 库文件 (C51S.LIB 中的启动代码 ?C_STARTUP 等)。
LINK MAP OF MODULE：
显示了各个段在内存中的分配情况，分为数据内存 (DATA MEMORY) 和代码内存 (CODE MEMORY) 两部分。
OVERLAY MAP OF MODULE：
显示了函数之间的调用关系，并分析了哪些函数可以进行 Overlay (覆盖)，从而节省 RAM。
SYMBOL TABLE OF MODULE：
列出了所有的符号 (包括变量、函数等)，及其地址、类型等信息。
WARNING 信息:
显示了编译器和链接器产生的警告信息。
内存空间占用分析：
DATA MEMORY：
REG 0000H 0008H ABSOLUTE "REG BANK 0"
表示寄存器区（Register Bank 0），起始地址为 0000H，大小为 0008H (8 字节)。
DATA 0008H 0048H UNIT ?DT?MAIN
表示 main.obj 模块中的 data 段，起始地址为 0008H，大小为 0048H (72 字节)。
通常包含已初始化的全局变量和静态变量。
DATA 0050H 0017H UNIT ?DT?UART0
表示 UART0.obj 模块中的 data 段，起始地址为 0050H，大小为 0017H (23 字节)。
通常包含已初始化的全局变量和静态变量。
DATA 0067H 0008H UNIT ?DT?TIMER0
表示 Timer0.obj 模块中的 data 段，起始地址为 0067H，大小为 0008H (8 字节)。
通常包含已初始化的全局变量和静态变量。
IDATA 006FH 0001H UNIT ?STACK
表示 stack 段， 起始地址为 006FH， 大小为 0001H (1 字节)，这非常小，表示你的栈空间很小，可能需要增加栈空间以避免堆栈溢出。
* `IDATA` 表示内部 RAM。
Use code with caution.
RAM 使用情况:
从DATA段来看，全局变量和静态变量总共使用了 8 + 72 + 23 + 8 = 111个字节。
从IDATA 段来看，栈使用了 1 字节。
总的RAM使用量为 112 个字节。
CODE MEMORY：
CODE 0000H 0003H ABSOLUTE
表示代码起始地址为 0000H， 占用3个字节，通常是启动代码。
CODE 0003H 0007H UNIT ?PR?UART0_ENABLE_INTERRUPT?UART0
表示 UART0_ENABLE_INTERRUPT 函数的代码段，起始地址为 0003H，占用7个字节。

OVERLAY MAP 分析：
作用： 可以查看程序中的函数调用关系，分析哪些函数可以覆盖使用内存空间，可以优化代码，减少RAM占用。
分析方法： 可以看到每个函数会调用哪些函数，方便我们分析调用关系和优化程序。
SYMBOL TABLE 分析：
作用： 可以查看所有变量和函数的定义和地址。
分析方法:
VALUE 表示地址，TYPE表示变量或者函数的类型，NAME表示名称。
D: 表示数据区， C: 表示代码区， B: 表示位变量。
可以看到每个变量的地址，从而确定哪些变量占用了RAM空间。
还可以看到变量的类型，方便我们分析变量的大小。
WARNING 信息分析：
WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS 表示某些代码段没有被调用，因此可以忽略掉，例如：
?PR?START_ALARM?MAIN: 表示 START_ALARM 函数没有被调用。
?PR?RESET_ALARM?MAIN: 表示 RESET_ALARM 函数没有被调用。
?PR?GET_CURRENT_TIME?TIMER0 : 表示 GET_CURRENT_TIME 函数没有被调用。
?PR?_UART0TX_WRITEONEBYTE?UART0 : 表示 _UART0TX_WRITEONEBYTE 函数没有被调用。
?PR?UART0_INIT?UART0 : 表示UART0_INIT函数没有被调用。
解决： 如果这些函数确实不需要被调用，可以删除或者注释掉，以免浪费代码空间。
总结：
这个 Map 文件提供了关于程序内存分配的详细信息，您可以从中了解到：
RAM 使用情况： 数据段使用了 111 字节的 RAM，栈使用了1字节的RAM， 可以看到，RAM资源使用很少，可能需要扩展栈空间。
代码空间占用： 代码段共占用 2550个字节。
函数调用关系： OVERLAY MAP 可以看到函数之间的调用关系。
未调用函数： WARNING 信息提示了一些未调用的代码段。
资源占用： 程序中声明的所有变量的地址和类型。
通过分析 Map 文件，您可以更好地了解程序运行时的内存使用情况，并进行代码优化，以避免内存溢出，提高程序效率。
希望这个详细的分析能够帮助您理解 Map 文件！如果您还有其他问题，请随时提出。芯片读回的程序（整个地址0x00000--0x00ff0）
