MOV AL, -5 ; AX = 000FBh (251). CBW. ; AX = 0FFFBh (-5). RET. CZSOPA unchanged. Clear Carry flag. Algorithm: CF = 0. Page 6 of 53. 8086 instructions OUT im.byte, AL im.byte, AX. DX, AL. DX, AX. Output from AL or AX to port. First operand is a port number. If required to access port number over 255 - DX register
Basic I/O Instructions. IN and OUT transfer data between an I/O device and the microprocessor's accumulator. (AL, AX or EAX). The I/O address is stored in: ? Register In the Isolated scheme, IN, OUT, INS and OUTS are required. . The I/O banks on the 8086 through the 80386SX are also set up like the memory. FFFF.
Write an 8086 assembly language procedure to send an ASCII character, stored in register AH, to a printer via PORT B of an 8255 PPI when PORT C bit PCO is strobed low and after an active low acknowledge signal is detected on PORT C bit PC5 from the printer. Assume a base address of 60H.

Used to send out a byte or word from the accumulator to the provided port.
Opcode. Instruction. Description. E6 ib. OUT imm8, AL. Output byte in AL to I/O port address imm8. E7 ib. OUT imm8, AX. Output word in AX to I/O port address imm8. E7 ib. OUT imm8, EAX. Output doubleword in EAX to I/O port address imm8. EE. OUT DX, AL. Output byte in AL to I/O port address in DX. EF. OUT DX, AX.

When you use the IN or OUT instructions, the M/#IO is not asserted (held low), so memory doesn't respond and the I/O chip does. For the memory-oriented .. Intel 8086 and 8088 and their clones also multiplex the data bus and address bus; all very uncommon stuff in CPUs. The datasheets are full of
Basic I/O Instructions. IN and OUT transfer data between an I/O device and the microprocessor's accumulator (AL, AX or EAX). Register DX as a 16-bit I/O address (variable addressing). The byte, p8, immediately following the opcode (fixed address).
8086 INSTRUCTION SET. DATA TRANSFER INSTRUCTIONS. MOV – MOV Destination, Source. The MOV instruction copies a word or byte of data from a specified source to a specified destination. The .. operation is desired as a rotate rather than shift, because the bit moved out of the LSB is rotated around into the MSB.
As the 8086 fetches instruction byte, the coprocessor also catches these bytes from data bus and puts them in its queue. The coprocessor treats all of the 8086 instruction as an NOP. When 8086 fetches an ESC instruction , the coprocessor decodes the instruction and carries out the action specified by the 6 bit code. In most
