Secondary Slave Trap (SST) — R/W. Enables trapping and SMI# assertion on legacy
I/O accesses to 170h-177h and 376h. The active device on the secondary interface
must be device 1 for the trap and/or SMI# to occur.
Secondary Master Trap (SPT) — R/W. Enables trapping and SMI# assertion on
legacy I/O accesses to 170h-177h and 376h. The active device on the secondary
interface must be device 0 for the trap and/or SMI# to occur.
Primary Slave Trap (PST) — R/W. Enables trapping and SMI# assertion on legacy I/
O accesses to 1F0h-1F7h and 3F6h. The active device on the primary interface must be
device 1 for the trap and/or SMI# to occur.
Primary Master Trap (PMT) — R/W. Enables trapping and SMI# assertion on legacy
I/O accesses to 1F0h-1F7h and 3F6h. The active device on the primary interface must
be device 0 for the trap and/or SMI# to occur.
