[User5327]

Hi all,
How can I change Rounding mode for float data type?
Is it possible?

(I use XMC4500)

Dear Koumak.

You may write to Rmode bitfield of FPDSCR register. This register is available in FPU_Type data structure defined in core_cm4.h.

Hi David,

You can use either “FPU -> FPDSCR” or “PPB -> FPDSCR” to access FPDSCR register since it is also defined in XMC4500.h under PPB_Type.
Moreover, the MVFR0 & MVFR0 registers contain a summary of supported FPU features.
