Input/Output Port Address Assignments
The CPU accesses input/output devices, such as modems, by read-
ing from them or writing to them. Each command to read or write
must specify the address (in memory) for the port. Each device
that communicates with the CPU must have a unique I/O port
address.
The following table lists the device names and their assigned I/O
