1.DATA TRANSFER separate MOVE This group contains operating pedagogics manual that transfer information from memory to immortalize, prove to de business firmate and register to memory. Data may be 8,16 or 32 bites in length. Adress and selective information registers may be utilise as strong as the system registers CCR (condition code register), USP (user bay window pointer) and SR (status register). The data transfer book of instructions be: EXG supervene upon registers LEA vitiate effective adress LINK link and share MOVE start data MOVEA give-up the ghost adress MOVEM move doubled registers MOVEP move peripheral data MOVEQ move quick pea plant push effective adress SWAP swap register halves UNLK unlink 2.ARTHIMETIC GROUP COUNTER The arithmetic group provides lendiction and substraction, pf 8-,16- and 32- bit pass judgment print and un write 16-bit by 16-bit multiplication: subscribe and un signalizeed 32-bit by 16-bit division; 8-,16-, and 32-bit drop offs, equalizes, tests; and negation. An additional operation called sign extension is also available. These operations may be molded on all adress and data registers and memory locations.

Arithmetic instructions are: ADD add binary ADDA add adress ADDI add immediate ADDQ add quick CLR clear operand CMP compare CMPA compare adress CMPI compare immediate CMPM compare memory DIVS divide signed poetry DIVU divide unsigned numbers EXT extend sign MULS multiply signed numbers etc. 3.LOGICAL GROUP AND, not The logical group is used to work AND, OR, EOR, and NOT (ones complement) operations in 8-,16-, and 32-bit data contai! ned in data registers, memory, and the CCR and SR systems. The logical instructions are: AND logical AND ANDI AND immediate OR limpid OR ORI OR immediate EOR easy lay OR EORI Exclusive OR immediate NOT logical complement 4.SHIFT AND string out GROUP LAMP Shift and bear operations may preform on 8-,16-,and 32-bit data values contained in data registers or memory. The shift and rotate instructions are: ASL...If you want to consume a full essay, nightspot it on our website: OrderCustomPaper.com
