NOTE:
The
following
discussion
applies
to
DOS
environment.
NODKA
support
is
contacted
or
the
NODKA
website
visited
for
specific
drivers
for
more
sophisticated
operating
systems,
e.g.,
Windows
and
Linux.
The
Watchdog
Timer
is
provided
to
ensure
that
standalone
systems
can
always
recover
from
catastrophic
conditions
that
cause
the
CPU
to
crash.
This
condition
may
have
occurred
by
external
EMIs
or
a
software
bug.
When
the
CPU
stops
working
correctly,
Watchdog
Timer
either
performs
a
hardware
reset
(cold
boot)
or
a
Non
‐
Maskable
Interrupt
(NMI)
to
bring
the
system
back
to
a
known
state.
A
BIOS
function
call
(INT
15H)
is
used
to
control
the
Watchdog
Timer.
INT

Sets
the
Watchdog
Timer’s
period.
BL:
Time

out
value
(Its
unit
‐
second
is
dependent
on
the
item
“Watchdog
Timer
unit
select”
in
CMOS
setup).

Sub

function
Call
sub
‐
function
2
to
set
the
time
‐
out
period
of
Watchdog
Timer
first.
If
the
time
‐
out
value
is
not
zero,
the
Watchdog
Timer
starts
counting
down.
When
the
timer
value
reaches
zero,
the
system
resets.
To
ensure
that
this
reset
condition
does
not
occur,
calling
sub
‐
function
2
must
periodically
refresh
the
Watchdog
Timer.
However,
the
watchdog
timer
is
disabled
if
the
time
‐
out
value
is
set
to
zero.
A
tolerance
of
at
least
10%
must
be
maintained
to
avoid
unknown
routines
within
the
operating
system
(DOS),
such
as
disk
I/O
that
can
be
very
time
‐
consuming.
NOTE:
When
exiting
a
program
it
is
necessary
to
disable
the
Watchdog
Timer,
otherwise
the
system
resets.
