Explain different types of IO instructions. Differentiate between I/O mapped and memory mapped I/O. [5]
I/O instructions are used by the CPU to communicate with input/output devices (peripherals). The main types are: - Transfers data from an I/O device (port) to the CPU (typically the accumulator). - The CPU reads data from the specified I/O port address. - Example: IN 01H -- reads data from port a...
