imm8 bit 1:0
intv		 Normalization Interval 00b _MM_MANT_NORM_1_2: 1 <= x < 2
01b _MM_MANT_NORM_p5_2: 0.5 <= x < 2
10b _MM_MANT_NORM_p5_1: 0.5 <= x < 1
11b _MM_MANT_NORM_p75_1p5: 0.75 <= x < 1.5
the mantissa is normalized to fit within the range specified.
imm8 bit 3:2
sgn		 Sign Control 00b _MM_MANT_SIGN_src: sign is unchanged
01b _MM_MANT_SIGN_zero: sign is set to positive
10b, 11b _MM_MANT_SIGN_nan: if sign of the source is negative, QNaN_Indefinite is stored as the result.
