11-10.
Comparator
11-10-1.
Comparator
types
and
functions
This
LSI
has
2
circuit
28-bit
comparators
per
axis.
These
are
referred
to
as
"Comparator1"
and
"
Comparator2."
Comparator
1
compares
the
setting
in
the
RCMP1
register
with
COUNTER1.
Comparator
2
compares
the
setting
in
the
RCMP2
register
with
COUNTER2.
One
of
three
comparison
methods
can
be
selected
(=,
<,
and
>),
and
the
comparison
results
can
be
output
to
a
terminal.
Also,
the
PCL
can
output
an
signal
such
as
an
event
interrupt
when
comparison
condition
is
met.
A
special
use
of
the
comparator
is
to
control
a
ring
count
function
and
internal
synchronized
start
function.
For
descriptions
of
these
functions,
see
"11-10-2.
Ring
count
function"
and
"11-11-2.
Start
on
an
internal
synchronized
signal."
Use
the
RENV2
and
RENV3
registers
to
set
the
comparators.
