SDM_pFlash Small

There is a different linker command file (LCF) for each target, which defines the destination
memory ranges used by the linker. Although the syntax of the LCF and C header files are
completely different. The LCF for each target is also used as prefix
configuration. The macros defined in the LCF identify the target for further conditional
compilation of the project source files.
The trick which enables using a file with the LCF syntax as a header file is shown on Code
Example 2-36. It successfully exploits the fact that the '#' sign is treated as a start of comment
line in LCF syntax, so the C-like #define statements do not cause the LCF syntax errors. On the
other side, the #if 0 ... #endif block excludes the LCF part of the file from C compilation.
1. Prefix file is unconditionaly included at the begining of every compiled C file.
