Memory Map Files

The linker can output memory map files (
that contain memory and symbol information for your executable file(s).
The map contains a summary of memory defined with
mands in the
.LDF
symbols.

Loader Output Files in Intel Hex-32 Format

The loader can output Intel hex-32 format files (
8-bit-wide PROMs and are used with an industry-standard PROM pro-
grammer to program memory devices. One file contains data for the
whole series of memory chips to be programmed.
The following example shows how the Intel hex-32 format appears in the
loader's output file. Each line in the Intel hex-32 file contains an extended
linear address record, a data record, or the end-of-file record.
:
020000040000FA

0402100000FE03F0F9
:
00000001FF
Extended linear address records are used because data records have a
4-character (16-bit) address field, but in many cases, the required PROM
size is greater than or equal to
records specify bits 31–16 for the data records that follow.
Table A-2 shows an example of an extended linear address record.
Table A-3 shows the organization of an example data record.
Table A-4 shows an end-of-file record.
