When
the
1x
to
32x
multiplication
circuit
is
set
to
3x
(PMG
=
2
on
the
RENV6),
operation
timing
will
be
as
follows.
When
the
n/2048
division
circuit
is
set
to
512/2048
(PD
=512
on
the
RENV6),
operation
timing
will
be
as
follows.
The
pulsar
input
mode
is
triggered
by
an
FL
constant
speed
start
command
(50h)
or
by
an
FH
constant
speed
start
command
(51h).
Pulsar
input
causes
the
PCL
to
output
pulses
with
some
pulses
from
the
FL
speed
or
FH
speed
pulse
outputs
being
omitted.
Therefore,
there
may
be
a
difference
in
the
timing
between
the
pulsar
input
and
output
pulses,
up
to
the
maximum
internal
pulse
frequency.
The
maximum
input
frequency
for
pulsar
signals
is
restricted
by
the
FL
speed
when
an
FL
low
speed
start
is
used,
and
by
the
FH
speed
when
an
FH
low
speed
start
is
used.
The
LSI
outputs
when
both
the
PA
and
PB
inputs
change
simultaneously,
or
when
the
input
frequency
is
exceeded,
or
if
the
input/output
buffer
counter
(deflection
adjustment
16-bit
counter
for
pulsar
input
and
output
pulse)
overflows.
This
can
be
monitored
by
the
REST
(error
interrupt
factor)
register.
