Note
The VXI/VME-MXI-2 has a limit on the number of automatic retries it will perform
on any one cycle. If the limit is exceeded and the VXI/VME-MXI-2 receives another retry,
it will pass a retry back to the MXIbus even though Auto Retry is enabled.

MXI Auto Retry

The VXI/VME-MXI-2 has an automatic retry feature for cycles that map
from the MXIbus to the VXI/VMEbus. This feature works in the same
manner as the Auto Retry control described in the
section. By default, this option is disabled.
Normally, when a cycle maps from the MXIbus to the VXI/VMEbus, any
retry response received on the VXI/VMEbus is passed to the MXIbus.
If you enable the Auto Retry feature, the VXI/VME-MXI-2 automatically
retries any VXI/VME cycle that receives a retry response instead of passing
a retry response on to the MXIbus. The VXI/VME-MXI-2 automatically
continues to retry the VXI/VME cycle until it receives either a DTACK or
BERR response, which it then passes to the MXIbus.
