Notes 1.

Includes cases where a file with the .c extension is compiled without specifying the -lang option.

Notes 2.

Includes cases where a file with the .cpp, .cp, or .cc extension is compiled without specifying the -lang option.

Notes 3.

Includes the specification by the ISA_RX environment variable.

Notes 4.

Always defined regardless of the option.

Notes 5.

When the Compiler version is VXX.YY.ZZ, the value of __RENESAS_VERSION__ is 0xXXYYZZ00.
Example
For V3.01.00: #define __RENESAS_VERSION__ 0x03010000
