#### 9.42.1 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`’.
