12 UTIL* Utility Signal Support
This read-only bit returns a 0 to indicate that the
VXI-MXI-2 supports routing of the VMEbus
utility signals ACFAIL*, SYSFAIL*, and
SYSRESET*. The value written to this bit is
irrelevant.
11-6 1 Reserved
These bits are reserved. They return 111111
(binary) when read. Write each of these bits with
1 when writing to the VUCR.
5 ACFIN ACFAIL* In
Setting this bit causes the VXI-MXI-2 to route
the ACFAIL* signal from the MXIbus to the
VXIbus. When this bit is clear, ACFAIL* is
ignored on the MXIbus. This bit is cleared by a
hard reset and is not affected by a soft reset.
4 ACFOUT ACFAIL* Out
Setting this bit causes the VXI-MXI-2 to route
the ACFAIL* signal from the VXIbus to the
MXIbus. When this bit is clear, ACFAIL* is
ignored on the VXIbus. You can route ACFAIL*
in both directions simultaneously. This bit is
cleared by a hard reset and is not affected by a
soft reset.
3 SFIN SYSFAIL* In
Setting this bit causes the VXI-MXI-2 to route
the SYSFAIL* signal from the MXIbus to the
VXIbus. When this bit is clear, SYSFAIL* is
ignored on the MXIbus. This bit is cleared by a
hard reset and is not affected by a soft reset.
2 SFOUT SYSFAIL* Out
Setting this bit causes the VXI-MXI-2 to route
the SYSFAIL* signal from the VXIbus to the
MXIbus. When this bit is clear, SYSFAIL* is
ignored on the VXIbus. You can route
SYSFAIL* in both directions simultaneously.
This bit is cleared by a hard reset and is not
affected by a soft reset.
