Override default device support
This selector allows you to indicate how Device Family Pack (DFP) management should be performed. The Do not override selection will let the MPLAB X IDE provide a list of DFPs that can be selected. If you would like to use a DFP that you have manually downloaded, select User specified location and then enter the path to the DFP in the Custom DFP path field. You may also select Compiler location, which will use the DFPs that ship with the compiler rather than the IDE.
Custom DFP path
If you have selected User specified location for the Override default device support option, enter the path to the DFP you wish to use in this field.
C standard
This selector specifies the language standard used. See 4.6.3.4 Std Option.
Output file format
This selector specifies the output file type. See 4.6.5.2 G: Produce Debugging Information Option.
Smart IO default Format
This field allows you to fine-tune the specifications that must be processed by smart IO functions when the compiler is unable to determine usage information from the formatted IO function cal. See 4.6.1.22 Smart-io-format Option
