WebFor memory-mapped I/O, decoding is identical to memory decoding. For isolated I/O, IORC and IOWC are developed using M/IO and W/R pins of the microprocessor. The text gives examples of 8-bit decoding and 16-bit decoding, which is a straightforward application of devices we've used for memory decoding.
