The
pammeten; for
the DSP's resistor all:
sel by sending
the
addre.~ses
and
data.
AfterlCS
is
set to
"L"
the resis tor's address
is
set for the first
and
second byte, and the data
is
set for the third
byte
and
thereafter.
The third
byle's
dmu
is
sent
\0 the
resistor
that was
set
with
the
first
and second
bytes. The
founh byte'
s
data
is
102
sem
to
the
resistor
whose
address
is one
above
(plus
one) the
address of
the
resisto
r
set
with
the
fir.>[
and
second
bytes.
For each
byte
of
data
sent,
the
address of the resis tor
set
with
the
fi~t
and
second
bytes will be
incremented.
Therefore,
continuous
addresses can
be
set
just by sending
the
data.
After the setting
is
completed,
JCS
will
become
"H."
