I want to use the DSP function on the MCU. Does Renesas's C Compiler M3T-CC32R for M32R family perform a compile to

generate instructions for the DSP function?

No, you cannot generate instructions for the DSP function from the C arithmetic expression using M3T-CC32R.

To obtain instructions for the DSP function from the C source, use the asm function (in-line assembly function*) and add the DSP

function instructions to the C source.

* The asm function is an extended function of M3T-CC32R and allows you to add any assembly code (such as

instructions for the DSP function) to the C source. For more details, please refer to the M3T-CC32R User's Manual [C
