Pulsar
(PA/PB)
input
mode
This
mode
is
used
to
allow
operations
from
a
pulsar
input.
In
order
to
enable
pulsar
input,
bring
the
terminal
LOW.
Set
POFF
in
the
RENV2
register
to
zero.
It
is
also
possible
to
apply
a
filter
on
the
input.
After
writing
a
start
command,
when
a
pulsar
signal
is
input,
the
LSI
will
output
pulses
to
the
OUT
terminal.
Use
an
FL
low
speed
start
(STAFL:
50h)
or
an
FH
low
speed
start
(STAFH:
51h).
Input
pulsar
signals
on
the
PA
and
PB
terminals.
The
input
specification
can
be
selected
from
the
four
possibilities
below
by
setting
the
PIM0
to
1
bits
in
the
RENV2
(environment
setting
2).
♦
Supply
a
90
˚ phase difference signal (1x, 2x, or 4x).
♦
Supply
either
positive
or
negative
pulses.
Shown
below
are
diagrams
of
the
operation
timing.
(RENV1:
PMD
=
100
---
When
outputting
2
pulses)
1)
When
using
90
o
phase
difference
signals
and
1x
input
(PIM
=
00)
2)
When
using
90
o
phase
difference
signals
and
2x
input
(PIM
=
01)
3)
When
using
90
o
phase
difference
signals
and
4x
input
(PIM
=
10)
4)
When
using
two
pulse
input.
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
(FP)
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
signals
as
errors
when
both
the
PA
and
PB
inputs
change
simultaneously,
or
when
the
input
frequency
is
exceeded,
or
if
the
input/output
buffer
counter
(4
bits)
overflows.
This
can
be
monitored
by
the
REST
(error
interrupt
factor)
register.
