On-Board
Programming
Mode
When
pins
are
set
to
on-board
programming
mode
and
a
reset-start
is
executed,
the
chip
enters
the
on-board
programming
state
in
which
on-chip
flash
memory
programming,
erasing,
and
verifying
can
be
carried
out.
There
are
two
operating
modes
in
this
ñ
boot
mode
and
user
program
mode
ñ
set
by
the
mode
pins.
Boot
mode
is
for
use
when
user
program
mode
is
not
available,
such
as
the
first
time
on-board
programming
is
performed,
or
if
the
program
activated
in
user
program
mode
is
accidentally
erased.
12.5.1
Boot
Mode
When
mode
pins
are
set
to
6
or
7
and
reset-start
is
executed,
the
HMS39C7092
enters
the
Boot
Mode
programming
state
in
which
on-chip
flash
memory
programming,
erasing,
verifying
can
be
carried
out.
There
are
two
operating
modes
in
this
mode
ñ
mode
6
is
extended
mode,
mode
7
is
one-chip
micro-controller
mode.
This
device
has
Internal
ROM
area
for
booting.
This
ROM
area
locates
in
0x00000000,
when
SBM(Serial
Boot
Mode)
=
ë1í
(i.e.
boot
mode
-
Mode6
or
7),
and
used
for
Serial
Boot
when
device
is
reset.
If
boot
mode
is
used,
a
flash
memory
programming
control
program
must
be
prepared
beforehand
in
the
host,
and
UART
channel
0
is
to
be
used.
When
a
reset-start
is
executed
after
setting
the
HMS39C7092
to
mode6
or
mode
7,
the
boot
program
in
is
activated
ñ
the
bit
rate
register
value
determined
to
38400
bps(in
33.86MHz),
then
on-chip
UART
receives
a
user
program
(flash
memory
programming
control
program)
from
off-chip.
The
received
user
program
is
written
into
RAM
(0x08030000~0x08030FFF).

6
or

7,

procedure.
