Here is the sample of MAP file from my test project...

My Unit (MainU) resides from 00232C28 to 00006998. Upto here, the memory address prefix with 0001. Starting from the next unit, it begins 0002 and so on.
What does it mean?
As well, what is 'C=', 'S=' 'G=' 'M=' and 'ACBP = '?

Map files are plain text files that contain information about the global symbols of your program, source file, and source line numbers useful for debugging.
sdata/sdata2 section is used for "small data" addressing.
The list file normally contains the assembly language code the compiler generated. It may also contain you original source code interspersed with the asm code. The map file contains all the static symbols (functions, globals, etc.) in your code and their relative addresses.
A mapfile is a text file that contains the following information about the program being linked: The module name, which is the base name of the file. The timestamp from the program file header (not from the file system)
The format is:SegmentId:StartAddress Length C=SegmentClass S=SegmentName G=SegmentGroup M=ModuleName
The ACBP has something to do with alignment but I can't tell you what the hex numbers mean.
C=CODE: Code-SegmentC=ICODE: Initialization Code-SegmentC=DATA: (initialized) Data-SegmentC=BSS: (uninitialized) Data-SegmentC=TLS: Thread Local Storage
G=(none): No Segment-Group
