Transfer
command
(1)
Source and
Destination
For
the
origin
(source)
ot
Transfer
command
K-RAM,
D-RAM
and
X
are provided.
Similarly, for
the destination
of
transfer
command
K-RAM,
DRAM
and
Y
are
provided.
Accordingly,
K-RAM
and
Serial I/O
output
registers
(O1H-02L)
can be
used
as
temporary
registers.
Combinations
are provided
as
follows.
{K-RAM,
DRAM)
->
Y
X
->
Y
X
_»
(K-RAM,
DRAM)
In
between
RAM
there
is
no
direct
transfer.
Even
if
there
is
a
transfer
command
to
Y. incase
it
is
not
actually
used,
Y
assignment uses
or
1.
B01H
to
B02L
for
X
and BI1H
to
BI2H
for
Y,
relate to
the
barrel
shifter
and
will
be
referred
to later
on.
X
and
Y
assignment can be
set
independently
for
the
transfer
command
of
single precision data.
For
the transfer
command
of
double
precision data,
X
and
Y
came
in
pair
as H/L
registers.
The
one
assigned
is
processed as
high
word
register.
Whether
the
transfer
command
is
of
single precision or
double
precision
depends on
the transfer
origin
(source).
That
is
determined
through
I23
and
I22bit
of
MPY
command.
MPY
command
uses
for
X*X,
16b*16b
(I23,
I22-LL,
1
cycle) or
32b*32b
(123,
I22=HH.
3
cycle).
Should
the
multiplication
be
ignored,
can be executed
at
16b*32b
(I23,
I22=LH, 2
cycle).
