Linking for Assembly Source File

Linking for Assembly Source File
Listing C-5 shows an example
describes a simple memory placement of an assembly source file. The file
in Listing C-4
from, L2 SRAM. This example assumes that the code and data declared in
L2 memory is cacheable within L1 code and data memories. The LDF file
includes two commands,
specific memory and system information. Refer to Notes for
on page 3-4 for information on items in this basic example.
Listing C-4. MyFile.ASM
.SECTION program;
.GLOBAL main;
main:
p0.l = myArray;
p0.h = myArray;
r0 = [p0++];
...
.SECTION data1;
.GLOBAL myArray;
.VAR myArray[256] = "myArray.dat";
