SFS = 0: SFSx is an input that synchronizes the
transmit superframe.
SFS = 1: SFSx is
an output indicating the
Transmit Superframe. In NT mode
SFSx is always an output.
NTS
LT / NT mode Select.
NTS = 0: LT mode selected
NTS = 1: NT modeselected
DMO
D channel Transfer mode Select.(
μ
W/DSI
only)
Significantonly when DEN=1.
DMO = 1: D channel data is shifted in and out on
Dx and Dr pins in continuousmode at
16 kbit/s on the falling and rising
edgesof 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 desable(GCI only).
T24D = 1: The timer watches at the exchangeon
MONITOR channel every time the UID
sends new byte. If it expires before
pre-acknoledgement,
message is generated; In this last
case, the aborted message is lost.
T24D = 0: The timer is desable. This means for
instance that UID may wait an pre-
acknoledgementfor ever.
DEN
D channel port Enable.(
μ
W/DSIonly)
an
abort
DEN = 0: D channel port disabled. D bits are
transferred on Br and Bx; Multiplexed
mode is selected automatically.
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
mode depending on DMO bit setting.
CID
: C/Ichanneldesable (GCI only).
CID = 0:
TXACT and RXACT registers only
accessiblevia the C/I channel.
Others registers only accessible via
MONITOR channel.
All registers only accessible via the
MONITOR channel.
ETC
2B+DData ExtendedTransparencychannel.
CID = 1:

line is
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
BP1equal 1 for repetor application.
BP1 = 0: The
activation
automatically processed without the
need of an AR command.
EIF
Error IndicationFilter.
Significant inNT modeonly
command
to
pursue
procedure
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 repetor application.
BP2 = 0: The activation procedure described
above
is
automatically
without the need of an AIcommand.
