Local Interrupt Enable Register
Local
Interrupt
Enable
Register
(LIER)
BAR2
(Offset
$14):
A
32
‐
bit
register
containing
a
group
of
interrupt
enables
corresponding
to
the
status
bits
in
LISR.
3.3.7 Network Target Data Register
Network
Target
Data
(NTD)
BAR2
(Offset
$18):
A
32
‐
bit
register
containing
the
data
associated
with
one
of
the
four
network
interrupts
that
will
be
sent
to
the
target
(destination)
node.
Writing
data
to
this
register
does
not
initiate
the
actual
interrupt;
only
writing
to
the
Network
Interrupt
Command
(NIC)
register
will
do
so.
The
NTD
register
is
both
read
and
write
accessible.
3.3.8 Network Target Node Register
Network
Target
Node
(NTN)
BAR2
(Offset
$1C):
An
8
‐
bit
register
containing
the
node
ID
of
the
target
(destination)
node.
Writing
to
the
NTN
register
does
not
initiate
the
actual
network
interrupt.
This
register
is
both
read
and
write
accessible.
The
NTN
register
can
be
written
or
read
with
the
Network
Interrupt
Command
Register
as
a
single
16
‐
bit
word.
