Comment
If the CODE field
indicates
OVERRUN and
CPU has serviced
the MB, when a
new frame is
moved to the MB,
the code returns to
FULL.
If the CODE field
already indicates
OVERRUN, and
another new frame
must be moved,
the MB will be
overwritten again,
and the code will
remain
OVERRUN. Refer
to Section
"Matching
Process" for details
about overrun
behavior.
