OMF-SPECIFIC LIBRARIES/START-UP MODULES
START-UP CODE
DSP LIBRARY
16-BIT PERIPHERAL LIBRARIES
Library files and start-up modules are specific to OMF (Object Module Format). An
OMF can be one of the following:
• COFF – This is the default.
• ELF – The debugging format used for ELF object files is DWARF 2.0.
There are two ways to select the OMF:
1. Set an environment variable called
2. Select the OMF on the command line when invoking the tool, i.e.,
16-bit tools will first look for generic library files when building your application (no OMF
specification). If these cannot be found, the tools will look at your OMF specifications
and determine which library file to use.
As an example, if

In order to initialize variables in data memory, the linker creates a data initialization
template. This template must be processed at start-up, before the application proper
takes control. For C programs, this function is performed by the start-up modules in

vided in corresponding

total, 49 functions are supported by the DSP Library.

The 16-bit software and hardware peripheral libraries provide functions and macros for
setting up and controlling 16-bit peripherals. These libraries are processor-specific and
of the form
