the address bus to select the I/O device at one of 256 possible ports. The
contents of Register B are placed on the top half (A8 through A15) of the
address bus at this time. Then one byte from the selected port is placed on
the data bus and written to register r in the CPU. Register r identifies any of
the CPU registers shown in the following table, which also indicates the
corresponding 3-bit r field for each. The flags are affected, checking the
input data.
