and_Data_16
This
packet
defines
a
group
of
logical
addresses
in
the
target
device
and
associates
logical
data
with
these
addresses.
The
addresses
comprise
a
linear
region
in
the
logical
address
space,
bounded
on
the
low
end
by
the
starting
address
and
extending
upward
by
the
address
count
specified
in
the
packet.

_and_Data
This
packet
defines
a
group
of
electrical
addresses
in
the
target
device
and
associates
data
values
with
those
addresses.
The
data
field
is
ordered
in
column-row
order,
beginning
with
the
data
for
the
least
column-row
address,
continuing
with
increasing
row
addresses
until
the
first
column
is
filled,
then
incrementing
the
column
address,
etc.

where
N

should
be
ignored.

This

The

The

Translation
Formats
Absolute
Binary
Format,
Code
16
Absolute
Binary
format
is
a
literal
representation
of
the
data
to
be
transferred
and
no
translation
of
the
data
takes
place
during
the
transfer.
There
are
no
overhead
characters
added
to
the
data
(i.e.
no
address
record,
start
code,
end
code,
nulls,
or
checksum).
Every
byte
transferred
represents
the
user's
data.
This
format
can
be
used
to
download
unformatted
data
such
as
an
“.exe”
file
to
the
programmer.
Since
this
format
does
not
have
an
end
of
file
character,
download
transfers
will
terminate
after
no
more
data
are
received
and
an
I/O
timeout
occurs.
This
is
true
for
all
data
formats
which
don't
have
an
end
of
file
indicator.
For
this
reason
do
not
use
a
value
of
0
for
the
I/O
timeout
parameter
on
the
communication
parameters
screen,
since
this
will
disable
the
timeout
from
occurring.
A
value
between
1
and
99
(inclusive)
should
be
used
for
the
I/O
timeout
parameter
when
using
formats
which
require
the
timeout
to
occur.
