I/O Write Transactions
I/O write transactions by definition are 32 bits.
sample I/O write transaction. The sequence of events is the same as 32-
bit single-cycle memory write transactions. The main distinction between
the two transactions is the command on the lt_cmdo[3..0] bus.

Adr-PAR
The PCI MegaCore functions do not ensure that the combination
of the ad[1..0] and cben[3..0] signals is valid during the
address phase of an I/O transaction. Local side logic should
implement this functionality if performing I/O transactions.
Refer to the PCI Local Bus Specification, Revision 3.0 for more
information on handling invalid combinations of these signals.
