6.3 OPTIONS
The command line options recognized by ASPIC[18] are given in Table 6-1, and a full
description of each option followings.
6.3.1 -A: Generate Assembly File
An assembler file will be produced if this option is used rather than the usual object file
format. This is useful when checking the optimized assembler produced using the -O
optimization option.
By default the output file will an extension .opt, unless the -Ooutfile output option
is used to specify another name.
6.3.2 -C: Specify Chip Info File
Specify the chipinfo file to use. The chipinfo file is called picc.ini and can be found
in the dat directory in the compiler’s installation directory. This file specifies information
about the currently selected device.
