; STRUCTURE OF THE INITIALIZATION INFORMATION
; -------------------------------------------
; This section describes the initialization data generated by C51 for
; explicit variable initializations (in segment ?C_INITSEC).
;
; Explicit variable initilizations at C source level are stored by C51 in
; the segment ?C_INITSEC.  All partial segments are combined at linker level
; to one segment.  The segment end value DB 0 is taken from this library module
; INIT.A51.
;
; Structure of the ?C_INITSEC information:
;    Info (see below) [BYTE]                   ----+  repeated
;    additional info  [BYTES depend on Info]    ----+  repeated
;    0x00          [BYTE] end of list mark
;
;  Info has the following format:
;
;  Bit    7  6  5  4  3  2  1  0
;  Info T  T  B  L  L  L  L  L T=Type  B=BIGBIT  L=LENGTH
;
;  If BIGBIT is set, another LENGTH BYTE FOLLOWS.  The LENGTH
;  info of the first byte is then the HIGH part.
;
;  Typ is one of the following:
;  0  := IDATA init values;  the following bytes follow:
;       -  1 byte address
;       -  init data bytes according LENGTH specification
;
;  1  := XDATA init values;  the following bytes follow:
;       -  2 byte address (high byte first)
;       -  init data bytes according LENGTH specification
;
;  2  := PDATA init values;  the following bytes follow:
;       -  1 byte address
;       -  init data bytes according LENGTH specification
;
;  3, BIGBIT=0  := BIT init values; the followign bytes follow:
;       -  1 byte for each bit according LENGTH specification
;          this byte has the following format:
;
;          Bit 7  6  5  4  3  2  1  0
;                I  B  B  B  B  B  B  B I := state of the bit
;                                        B := bit address
;
;  3, BIGBIT=1  := HDATA init values; the following bytes follow:
;       -  another LENGTH byte (since BIGBIT is always 1)
;       -  3 byte address  (MSB first)
;       -  data bytes according LENGTH specification
;

哈哈，从某编译器里某个文件里摘录出来的，程序的一部分，和startup.a51一样，可以不用加入到工程里。
最近一个程序，两个版本，切换了兼容老版本的编译器开关后，通过整理后的hex对比发现，只有一个bit不一样，源代码对比了一个上午没有发现哪里会导致不一样。后来在这个文件里跟踪了老久，终于发现是某个bit类型的变量初始值不一样，从list文件和map文件直接找到了这个变量的名字。
本来自己把汇编窗口里注释了一遍，后来发现原来这个文件里有更详细的说明，大家看看是那个文件里的？

把您电脑里的这个文件的目录+文件名放在跟帖里，第一个对的的全分，后面的没有分数。
最近竞猜很火的说。
