SFS = 0: SFSx is an input that synchronizes the
transmitsuperframe.
SFS = 1: SFSx is an
Transmit Superframe. In NT mode
SFSx is always an output.
NTS
LT / NT mode Select.
NTS = 0: LT mode selected
NTS = 1: NT mode selected
DMO
D channel Transfer mode Select.(

output indicating the
DMO = 1: D channel data is shifted in and out on
Dx and Dr pins in continuous mode at
16 kbit/s on the falling and rising
edges of DCLK respectively.
DMO = 0: D channel data is shifted in and out on
Dx and Dr pins in a TDM mode at the
BCLK frequency on the falling and
rising edges of BCLK respectively
when the assigned time-slots are
active.
T24D:
24mstimer disable (GCIonly).
T24D = 1: The timer watches at theexchange on
MONITOR channeleverytime the UID
sends new byte. If it expires before
pre-acknoledgement,
message is generated; In this last
case, the abortedmessageis lost.
T24D = 0: The timer is desable. This means for
instance that UID may wait an pre-
acknoledgementfor ever.

DEN = 0: D channel port disabled. D bits are

modeis selectedautomatically.
DEN = 1: D channel port (DX, DR, and DCLK
when DMO bit equal 1) is selected. D
bits are transferred on Dr and Dx in a
modedepending on DMO bit setting.
CID
: C/I channeldisable(GCI only).
CID = 0:
TXACT and RXACT registers only

Others registers only accessible via
MONITOR channel.
All registers only accessible via the
MONITOR channel.

the line
ETC = 0: 2B+D channel transparency is under
control of the on-chip state machine:
act bit equal one both directions.
BP1
Break Point 1 during activation(significative
only when NTS = 0: LT mode) .
BP1 = 1: During an activation attempt from the
loop, (before SL2 sending) UID waits
for
an
AR
activation. It is recommended to set
BP1 equal 1 forrepetor application.
BP1 = 0: The
activation
automatically processed without the
need of an ARcommand.
EIF
Error IndicationFilter.

is
EIF = 0:
act bit is set to zero in the transmit
superframe in case of EI command,
even if EI is sent sporadically.
act bit may be not set to zero in the
transmit superframe in case of EI
command with a duration of less than
36ms.
BP2
Break Point 2 during activation. Significant
only when NTS=0 (LT selected)
EIF = 1:
BP2 = 1: During a full activation procedure, UID
receiving
act bit set to one in the
received SN3 signal, UID waits for an
AI command to send act bit equal one
in SL3 signal. It is recommended to set
BP2 equal 1 for repetorapplication.
BP2 = 0: The activation procedure described
above
is
