WAIT_FOR_DEACT
Specifies
whether
the
controller
should
wait
for
the
input
trigger
to
be
deactivated;
i.e.
the
selected
system
trigger
is
not
active.
This
field
is
used
to
synchronize
the
controller
with
the
agent
that
generated
the
trigger.
This
field
is
ONLY
used
at
the
completion
of
the
transfer
as
specified
by
TR_IN.
E.g.,
a
TX
FIFO
indicates
that
it
is
empty
and
it
needs
a
new
data
sample.
The
agent
removes
the
trigger
ONLY
when
the
data
sample
has
been
written
by
the
controller
AND
received
by
the
agent.
Furthermore,
the
agent's
trigger
may
be
delayed
by
a
few
cycles
before
it
reaches
the
controller.
This
field
is
used
for
level
sensitive
trigger,
which
reflect
state
(pulse
sensitive
triggers
should
have
this
field
set
to
'0').
The
wait
cycles
incurred
by
this
field
reduce
DW
controller
performance.
'0':
Do
not
wait
for
trigger
de-activation
(for
pulse
sensitive
triggers).
'1':
Wait
for
up
to
4
cycles.
'2':
Wait
for
up
to
16
cycles.
'3':
Wait
indefinitely.
This
option
may
result
in
controller
lockup
if
the
trigger
is
not
de-activated.
Copy
of
DESCR_CTL
of
the
currently
active
descriptor.
