#### 9.31.1 Options

The TMS320C54X version of `as` has a few machine-dependent options.

You can use the ``-mfar-mode`' option to enable extended addressing mode. All addresses will be assumed to be > 16 bits, and the appropriate relocation types will be used. This option is equivalent to using the ``.far_mode`' directive in the assembly code. If you do not use the ``-mfar-mode`' option, all references will be assumed to be 16 bits. This option may be abbreviated to ``-mf`'.

You can use the ``-mcpu`' option to specify a particular CPU. This option is equivalent to using the ``.version`' directive in the assembly code. For recognized CPU codes, see See `.version`. The default CPU version is ``542`'.

You can use the ``-merrors-to-file`' option to redirect error output to a file (this provided for those deficient environments which don't provide adequate output redirection). This option may be abbreviated to ``-me`'.
