    They are not in ROM any more , because we have TMU and instructions like sin and cos etc have CPU instructions that perform this.

    If you need to use these for some reason you will have to use some RAM space to copy these..

    FPUmathTables : > RAMGS3, PAGE =1

    Note, if you run from flash, make sure you assign the abve to flash and then copy from flash to RAM during init function.
