Pin Mapping

There are three ways to describe the pin mapping of the XJLink connector:

1. Provide the name of a Pin Mapping File (.xjpm) that describes the mapping.

   // User-defined pin map in separate file
   JTAG CHAIN
       CONNECTOR "JTAG Header"
           TDI := CN12.5;
           TDO := CN12.6;
   
           PINMAP "custom.xjpm";
       END;
   END;
   

2. Use a standard pin mapping (one of BYTEBLASTER, MULTIICE, XILINX or XJTAG).

   // Built-in standard pin map.
   JTAG CHAIN
       CONNECTOR "JTAG Header"
           TDI := CN12.1;
           TDO := CN12.2;
   
           MAPPING
               XJTAG;
               POWER := ON;
           END;
       END;
   END;
       

3. Specify a custom pin mapping, using the same syntax as a pin mapping file, e.g. by pasting the contents of the *.xjpm file into the preamble file.

   // User-defined pin map inline
   JTAG CHAIN
       CONNECTOR "JTAG Header"
           TDI := CN12.7;
           TDO := CN12.8;
   
           MAPPING
               TDI := 1 HI;
               TDO := 3;
               TMS := 5 HI;
               TCK := 6 HI;
               LOW := 7 HI;
   
               TRST := 8;
           END;
       END;
   END;
