Instruction works as follows : If the value of the low — order four bits (D 3-D 0) in the accumulator is greater than 9 or if auxiliary carry flag is set, the instruction adds 6 (06) to the low-order four bits. instructions over 8086/8088. 0 Andrew Waterman, Yunsup Lee, David Patterson, Krste Asanovi c CS Division, EECS Department, University of California, Berkeley Condition: New. the 8086 use this mode to reference an operand in memory. The instruction set of a microprocessor is the collection of the instructions that the microprocessor is designed to execute. There is one more minor difference in one of the control signals. Instruction set of 8088 processor consists of the following instructions: Data moving instructions.
