Unused Pins

CODSP:
Pins which are not used in the applica-
tion should be connected as described
here. Failure to do so could result in
excessive sensitivity to RFI, or other
erratic behaviour. '0' or '1' indicates
that the pin should be connected to
ground or to the device's digital supply.
'-' indicates that the pins is an output
and must be left unconnected.
SHLIC:
The pins NC (7, 8, 21 and 22) are
connected to the device substrate,
which is at a voltage equal to the
VBATR supply pin, and may optionally
be electrically connected to this pin.
The pin BAT is the internal supply to the
line-drivers, and adopts the voltage of
VBATR or VBATS, plus the voltage drop
across the internal switch, depending
on the operating mode. In low-voltage
only systems (very short connections,
the pins BAT, VBATR and VBATS may
all be connected together, and a single
supply (e.g. -27V) used for both ringing
and speech modes. (In this mode, the
voltage drop of the internal switches is
avoided).
