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.
