Description

Floating-point Default Status Control Register

Fields

RMode

Default value for FPSCR.RMode (Rounding Mode control field).

0 (00): Round to Nearest (RN) mode

1 (01): Round towards Plus Infinity (RP) mode.

2 (10): Round towards Minus Infinity (RM) mode.

3 (11): Round towards Zero (RZ) mode.
FZ

Default value for FPSCR.FZ (Flush-to-zero mode control bit).

0 (0): Flush-to-zero mode disabled. Behavior of the floating-point system is fully compliant with the IEEE 754 standard.

1 (1): Flush-to-zero mode enabled.
DN

Default value for FPSCR.DN (Default NaN mode control bit).

0 (0): NaN operands propagate through to the output of a floating-point operation.

1 (1): Any operation involving one or more NaNs returns the Default NaN.
AHP

Default value for FPSCR.AHP (Alternative half-precision control bit).

0 (0): IEEE half-precision format selected.

1 (1): Alternative half-precision format selected.
