Converts half type data to int16_t, and supports multiple rounding modes.

• RINT rounding mode: round half to even
• ROUND rounding mode: round half up
• FLOOR rounding mode: round toward negative infinity
• CEIL rounding mode: round toward positive infinity
• TRUNC rounding mode: round toward zero

Based on the magnitude of the input data, the operation is divided into non-saturating mode and saturating mode.

• Non-saturating mode:
  • When the input data exceeds the maximum or minimum value of the output type, the result is truncated to the data width of the target format.
  • When the input data is +/-inf, the maximum or minimum value of the output type is returned.
  • When the input data is nan, 0 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 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 .
