3.5.3 -p,
            --processor=PROC
   
   Specify the target processor, e.g.:
xc-dsc-as -p30F2010 file.s
      The assembler defines macros based on the target processor setting, which
         can be tested by conditional directives in source code. For example, include file
            p30F2010.inc contains the following:
.ifndef __30F2010 
 .error “Include file does not match processor setting”
.endif
      In addition to the target processor, a macro to identify the device family is also defined. For example:
.ifdef __dsPIC30F
 .print “dsPIC30F family selected”
.endif
      Macros for the device families (see Section 3.5.6 “Predefined Symbols”) are defined based on target processor setting.
