  • Non-saturating mode:
    • When the input data exceeds the maximum or minimum value of the output type, the corresponding signed inf value of the output type is returned.
    • When the input data is +/-inf, +/-inf is returned.
    • When the input data is nan, nan is returned.
  • Saturating mode:
    • When the input data exceeds the maximum or minimum value of the output type, the corresponding maximum or minimum value of the output type is returned.
    • When the input data is +/-inf, the corresponding maximum or minimum value of the output type is returned.
    • When the input data is nan, 0 is returned.
  • To enable the saturating mode and non-saturating mode, you need to configure the ctrl register. For details about the ctrl register, see .
