For
use
with
this
interface,
the
Prophet
maintains a
pointer to
NV RAM
addresses
which
allows
implied
addressing
of the
file.
The
pointer
initially
indicates the
first
NV
RAM
address
(0).
Whenever
the
Prophet
receives a
code
08(H), it
outputs the
NV
RAM
byte
currently
being
pointed
to, then
increments
the
pointer.
Therefore to read
all of
the
NV
RAM
file,
the
sequencer
will have
to
supply
exactly
1024
(960
program bytes
+
64 unused
bytes)
STATUS 3
requests.
This will
leave the
pointer
reset at address 0.
To
access
specific
programs,
send
the
number of
STATUS 3's
required
to increment the
pointer
to
the
desired
starting
address,
and
simply ignore
the
intermediate
data
which
the
Prophet
returns.
Any
error
detected
by the
Prophet's
receiver
resets the
NV RAM pointer
to
address
0.
6-8
STATUS
*:
LOAD
FROM
TAPE
This status
byte
is used to
initiate
a
file
loading of NV
RAM. When the Prophet
receives
code
10(H),
it sets
itself to
T^PE READ mode,
in
which
it expects to receive
exactly 2048 bytes.
This
will be
the entire
40-program
data
block (+64
unused bytes)
sent
twice,
without
interruption.
The first
byte received
will be placed in the
NV
location
indicated by
the
pointer.
The
Prophet
will not recognize
status bytes again
until
all
2048 bytes
have
been
received,
or
an error occurs.
The error clears
TAPE
READ
mode and
resets the
NV
pointer
address
0.
To load
NV RAM,
the
Prophet's
back
panel
RECORD
switch must be
ENABLED.
6-9
STATUS 5:
CLEAR
TRANSPOSE
Code
20(H)
turns
off the
TRANSPOSE
function
enabled
by Status 2. It also returns the
sequence to
its
original
key.
6-10
STATUS
6:
INITIALIZE
SEQ
LOWER
PROGRAM
This
status
byte
40(H)
was
inherited
from the
Prophet-10
but should
not
be
sent
to the
Prophet-5.
