Count/Register field:
dr field—Specifies the direction of the rotate.
Size field—Specifies the size of the operation.
i/r field—Specifies the rotate count location.
Register field—Specifies a data register to be rotated.
X — Not affected.
N — Set if the most significant bit of the result is set; cleared otherwise.
Z — Set if the result is zero; cleared otherwise.
V — Always cleared.
C — Set according to the last bit rotated out of the operand; cleared when the rotate
If i/r = 0, this field contains the rotate count. The values 1 – 7 represent counts of 1
If i/r = 1, this field specifies a data register that contains the rotate count (modulo 64).
0 — Rotate right
1 — Rotate left
00 — Byte operation
01 — Word operation
10 — Long operation
If i/r = 0, immediate rotate count.
If i/r = 1, register rotate count.
