CHAPTER 6 DETAILED RULES FOR EXECUTION INSTRUCTIONS
6.42 MOV (MOVE Byte Data from Memory to Accumulator)
Transfer byte data from EA memory (memory expressed in each type of addressing) to A. Byte data in AL is transferred to TL. AH is not changed.
■MOV (MOVE Byte Data from Memory to Accumulator)
Operation
(AL) ← (EA) (Byte transfer)
Assembler format
