(CX20152)
format.
One

for input
and
output, o'perate
in
common
synchronously
with external
LRCK
and
BCK,
Each
inputs
and
outputs data
for
2ch
at
every
sample
cycle.
For
bit
clock
BCK
there are
2
kinds.
32
bit
clock
mode
and 24
bit
clock
mode.
Data
format
is
in
complement on
2
positive logic
binary
fixed
decimal
point type.
There
is
32
bit/24 bit/16
bit
data according
to
the various
modes.
Transfer order
for
each and
all
is
at
the
last

For output
register either
read

available.
For
use as
single precision
(16
bit)
register,
the
above
8
registers
can
all
be
handled
independently. For instance
when
11

is
specified the
numerical expression
becomes,
A31
at
MSB
(sign

and
Aie

come
in
pairs.
For
instance
when
