//   HEAP       -- The heap used by malloc and free in C and new and

//   INITTAB    -- Table containing addresses and sizes of segments that

//                 an absolute location given by the @ operator or the 
//                 #pragma location directive. Since these segments 
//                 contain objects which already have a fixed address, 
//                 they should not be mentioned in this linker command 
//                 file. 
//   _C         -- Constants (ROM). 
//   _I         -- Initialized data (RAM).

//   _N         -- Uninitialized data (RAM). 
//   _Z         -- Zero initialized data (RAM). 
// 
// Note:  Be sure to use end values for the defined address ranges. 
//        Otherwise, the linker may allocate space outside the 
//        intended memory range.

// Segment placement - General information 
// 
// All numbers in the segment placement command lines below are interpreted 
// as hexadecimal unless they are immediately preceded by a '.', which 
// denotes decimal notation.  
// 
// When specifying the segment placement using the -P instead of the -Z 
// option, the linker is free to split each segment into its segment parts 
// and randomly place these parts within the given ranges in order to 
// achieve a more efficient memory usage. One disadvantage, however, is 
// that it is not possible to find the start or end address (using 
// the assembler operators .sfb./.sfe.) of a segment which has been split 
// and reformed.  
// 
// When generating an output file which is to be used for programming 
// external ROM/Flash devices, the -M linker option is very useful  
// (see xlink.pdf for details).
