The EA of the instruction must bean even address in order for the instruction to perform asdescribed. If the EA is odd, the contents of A are storedat the EA and the contents of Q are not stored. In anycase, the contents of A and Q remain unchanged.THE CARRY AND OVERFLOW INDICATORS are notchanged by this instruction.EXAMPLES VR.M.,1,7NVOBE:rATAW111;-'2,;;Q5Assembler Language CodingEquivalent Machine Language InstructionLabel21 25Operation27 30FT323335 40SeeNoteHexadecimalValueDescriptionFormat, , SITID, D11 ,S IP, 1 I D8XX Contents of A and Q are stored in CSL at EA (I + DISP) andi 1 , 1 I, , 1 1EA + 11 1 I S IT I D, I DI I IS ,P, 1 1 1 1 D9XX Contents of A and Q are stored in CSL at EA (XR1 + DISP)I [ 1 1 1 I 1 1 1 1 1 1t 1 and EA + 11 S IT I D, 2 D,I,S,P, i DAXX Contents of A and Q are stored in CSL at EA (XR2 + DISP)1 1 i 1 i 1 i 1 i and EA + I, 1 SIT,D1 3 D 1 I,S,P 1 I I 1 DBXX Contents of A and Q are stored in CSL at EA (XR3 + DISP)I I I I I i i I i 1 and EA + 11 1 I S IT ID, L A I D ,D,R, • , DCOOXXXX Contents of A and Q are stored in CSL at EA (Addr) andI ii / 1 i 1 1 1 1 1 EA + 1i , SIT ID, L I A,D ,D,R, 1 DDOOXXXX Contents of A and Q are stored in CSL at EA (Addr + XR I)I I 1 1 1 I 1 1 1 I and EA + 11 1 S,T,D, L 2 A ID ,D,R 1 DE00XXXX Contents of A and Q are stored in CSL at EA (Addr + XR2)1 1 1 1 1 1 1 1 1 1 1 1 1 1 and EA + 11 1 SIT,D, L 3 A,D,D I RI 1 I DFOOXXXX Contents of A and Q are stored in CSL at EA (Addr + XR3)I i I i i i 1 1 1 1 1 1 1 1 and EA + 1I 1 I SITIDI I A,D,D,R, 1 1 I I DC80XXXX Contents of A and Q are stored in CSL at EA (V in CSL at1 1 I 1 1 1 1 1 1 i I I 1 I Addr) and EA + 11 I I S,T,D, I I A,D,D,R, 1 DD80XXXX Contents of A and Q are stored in CSL at EA (V in CSL atI I I I I I t I I I "Addr.+ XR I") and EA + 11 i STD I122 A,D,D,R, , DE80XXXX Contents of A and Q are stored in CSL at EA (V in CSL at. 1 1 1 !III , "Addr + XR2") and EA + 1I t1 DF80XXXX Contents of A and Q are stored in CSL at EA (V in CSL at1 I I I I I III1"Addr + XR3") and EA + I',,, S,T,D , I 3 A,D,D,R,ShortInstructionLongInstructionDirectAddressingLongInstructionIndirectAddressingInstruction Set 19STD
