Inb outb
WebDescription. Copies the value from the second operand (source operand) to the I/O port specified with the destination operand (first operand). The source operand can be register AL, AX, or EAX, depending on the size of the port being accessed (8, 16, or 32 bits, respectively); the destination operand can be a byte-immediate or the DX register. WebA delay can be counted in bus cycles. > >> In the real world, driver authors aren't perfect and will have used >> outb_p as a wall-clock delay which they have gotten away with since >> it's a nicely specified delay in terms of the ISA/LPC clock and the >> ISA/LPC clock being fairly (old) to very (new) constant. > > It's most commonly a zero delay.
