+## CC-RX compiler for C and CPP
+
+Cross-compilation is now supported for Renesas RX targets with the CC-RX compiler.
+
+The environment path should be set properly for the CC-RX compiler executables.
+The `-cpu` option with the appropriate value should be mentioned in the cross-file as shown in the snippet below.
+
+```ini
+[properties]
+c_args      = ['-cpu=rx600']
+cpp_args    = ['-cpu=rx600']
+```
+
+The default extension of the executable output is `.abs`.
+Other target specific arguments to the compiler and linker will need to be added explicitly from the cross-file(`c_args`/`c_link_args`/`cpp_args`/`cpp_link_args`) or some other way.
+Refer to the CC-RX User's manual for additional compiler and linker options.
