The
FIQ
status
register
is
used
to
reflect
the
status
of
all
channels
set
to
produce
an
FIQ
interrupt
(IDR
n
=
1).
When
an
interrupt
is
set
for
an
FIQ
occurring,
the
corresponding
bit
is
set
in
FIQ
status
register.
The
interrupt
handler
will
examine
this
register
to
determine
the
channel(s)
that
caused
the
FIQ
interrupt.
When
the
status
clear
register
is
written
to
ë1í,
the
corresponding
bit
is
cleared
if
that
channel
is
configured
to
edge
trigger
mode.
A
HIGH
bit
indicates
that
the
interrupt
is
active
and
will
generate
an
interrupt
to
the
processor.

The
FIQ
request
mask
register
is
used
to
mask
the
request
to
generate
an
interrupt
to
a
processor.
If
certain
bits
within
the
interrupt
controller
are
not
implemented,
the
corresponding
bits
in
the
FIQ
request
mask
register
must
be
masked.
A
bit
value
0
indicates
that
the
interrupt
is
unmasked
and
will
allow
an
interrupt
request
to
reach
the
processor.
A
bit
value
1
indicates
that
the
interrupt
is
masked.
On
reset,
all
FIQ
requests
are
unmasked.
