Count/Register field
dr field—Specifies the direction of the shift.
Size field—Specifies the size of the operation.
Register field—Specifies a data register to be shifted.
X — Set according to the last bit shifted out of the operand; unaffected for a shift
N — Set if the result is negative; cleared otherwise.
Z — Set if the result is zero; cleared otherwise.
V — Always cleared.
C — Set according to the last bit shifted out of the operand; cleared for a shift count
If i/r = 0, this field contains the shift count. The values 1 – 7 represent shifts of 1 – 7;
If i/r = 1, the data register specified in this field contains the shift count (modulo 64).
0 — Shift right
1 — Shift left
00 — Byte operation
01 — Word operation
10 — Long operation i/r field
If i/r = 0, specifies immediate shift count.
If i/r = 1, specifies register shift count.
