Memory-mapped I/O is preferred in x86-32 and x86-64 based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or destination port of the transfer.
James Jacob Ritty Reproduction of Ritty Dial, the first practical cash register. James Jacob Ritty (29 October 1836 – 29 March 1918), saloonkeeper and inventor, opened his first saloon in Dayton, Ohio in 1871, billing himself as a "Dealer in Pure Whiskies, Fine Wines, and Cigars."

Control register. A control register is a processor register that changes or controls the general behavior of a CPU or other digital device. Common tasks performed by control registers include interrupt control, switching the addressing mode, paging control, and coprocessor control.
A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor.Examples of such registers include FLAGS register in the x86 architecture, flags in the program status word (PSW) register in the IBM System/360 architecture through z/Architecture, and the application program status register (APSR) in the ARM Cortex-A architecture.
