Overview

Mode setting intrinsics to get and set bits in the control and status register.

The rounding and saturation in the srs intrinsics (Shift-Round-Saturate) is controlled through special mode setting commands.

Modules
	Control registers
	Intrinsics to set,get and clear the control registers.

	Status registers
	Intrinsics to set,get and clear the status registers.

Rounding Modes

#define	rnd_floor 0
	No rounding - Truncate LSB, always round down (towards negative infinity)

#define	rnd_ceil 1
	No rounding - Always round up (towards positive infinity)

#define	rnd_sym_floor 2
	No rounding - Truncate LSB, always round towards 0.

#define	rnd_sym_ceil 3
	No rounding - Always round up towards infinity.

#define	rnd_neg_inf 8
	Round halfway towards negative infinity.

#define	rnd_pos_inf 9
	Round halfway towards positive infinity.

#define	rnd_sym_zero 10
	Round halfway towards zero (away from infinity)

#define	rnd_sym_inf 11
	Round halfway towards infinity (away from zero)

#define	rnd_conv_even 12
	Round halfway towards nearest even number.

#define	rnd_conv_odd 13
	Round halfway towards nearest odd number.
