Post rotation mode
PostRotMode[3:0] = {HorMir, VerMir,
RotAng[1:0]}
HorMir : Horizontal mirroring
VerMir : Vertical mirroring
RotAng[1:0]
0 : 0 degree counterclockwise rotate
1 : 90 degree counterclockwise rotate
2 : 180 degree counterclockwise rotate
3 : 270 degree counterclockwise rotate
If this field is 4'b0000, post rotation is enabled
but just copy the decoded image
