MOV3Q Move 3-Bit Data Quick MOV3Q
Operation: Immediate Data → Destination
Assembler Syntax MOV3Q #<data>,<ea>x
Attributes: Size = long
Description: Move the immediate data to the operand at the destination location. The data
range is from -1 to 7, excluding 0. The immediate data is zero-filled to a long operand and
all 32 bits are transferred to the destination location.
Condition Codes:
Instruction Fields:
• Data field—3 bits of data having a range {-1,1-7} where a data value of 0 represents
-1.
• Effective Address field—Specifies the destination operand; use only data addressing
modes listed in the following table:
X N Z V C X Not affected
N Set if the result is negative; cleared otherwise
Z Set if the result is zero; cleared otherwise
V Always cleared
C Always cleared
