OUTPUT
SIGNAL
GENERATING
CONDITIONS
Conditions
for
generating
output
signal
are
described
in
(1).
Conditions
for
setting
and
resetting
the
operational
mem-
ory
in
the
SYS-CON
are
described
in
(2).
Resetting
has
priority
over
all
other
operations
in
the
SYS-CON.
There-
fore,
even
if
a
set
condition
exists,
the
corresponding
mem-
ory
will
not
be
set
if
a
reset
conditions
exists.
Signs
used
in
(1)
and
(2)
are
as
follows,
except
tor
those
indicated
in
Fig.
2.
F**
(**
are
numerals):
Flip-flops
functioning
as
memories.
S**,
R**:
Confitions
for
setting
and
resetting
F**.
Q**:
Output
of
F**
which
rises
to
the
high
level
when
F**
is
set.
DL:
Delay.
This
condition
is
established
when
the
delay
time
described
in
the
paragraph
1.3,
(2)
elapses.
All
formulas
established
in
the
SYS-CON
are
expressed
by
logical
equations
of
AND
and
OR.
“|”
means
AND
“+
>
means
OR
(Example)
RCO
=
Q0l
SOl1
=
RCI.
(PYI
+
SBI)
The
above
equations
means:
RCO
(record
output
terminal,
pin
16)
of
the
SYS-CON
goes
high
when
QO1
is
high.
QO1
goes
high
when
the
REC
operation
memory
F@I
is
set.
FO1
is
set
when
the
set
condition
S01
is
established.
SO1
is
established
when
RCI
is
high
and
PYI
or
SBI
is
high.
That
is,
Fol
is
set
when
the
REC
button
is
depressed
together
with
the
PLAY
or
PAUSE
button,
and
the
output
QO1
goes
high
and
thus
RCO
goes
high
so
the
REC
operation
signal
is
output.
The
bar
“‘—”
in
PY]
and
RES
means
the
low
level,
and
each
of
these
signs
indicates
the
condition
where
the
PLAY
button
is
not
depressed,
and
the
condition
where
no
reset
signal
exists.
In
the
logical
formulas
in
(1)
and
(2),
the
first
equation
line
out
of
two
lines
is
the
general
equation
of
the
SYS-CON.
The
second
line
is
the
equation
applied
to
the
C-1.
Since
pins
11
to
14
of
the
SYS-CON
are
grounded
in
C-1,
input
signals
of
RVW,
MN1,
R/M2
and
MOD
are
usually
at
the
low
level.
If
the
general
equation
is
modified
taking
ac-
count
of
this
fact,
it
becomes
the
same
as
the
equation
for
C-1.
