FUNCTION
Bus Master Enable
TYPE
RW
DESCRIPTION
Bus Master Control
0:
PI7C21P100 does not initiate memory and I/O transactions on the
primary and disables responses to memory and I/O transactions on
the secondary
1:
Enables PI7C21P100 to operate as a master on the primary for
memory and I/O transactions forwarded from the secondary.
In PCI-X mode, PI7C21P100 is allowed to initiate a split completion
transaction regardless of the status of this bit. Reset to 0
Memory Space Control
0:
Ignore memory transactions on the primary
1:
Enables responses to memory transactions on the primary
Reset to 0
I/O Space Control
0:
Ignores I/O transactions on the primary
1:
Enables responses to I/O transaction on the primary
Reset to 0
