Description
Remote febe select:
When tied to 0 the remote febe is not transferred. When tied to 1febe is
transparently reported. See figure 10.
TxSuper framesynchronization. In LTmode thispin is aninput giving the Tx
SuperFrame Synchronization if SFS= 0 in CR2.It becomes an output if SFS
= 1 withISW free running on the line. In NT mode this pinis always an output
giving the TxSuperFrame position. If DECTmode is selected (DECT = 1in
CR7) thispin provide the DECT synchronization pulse at eachvalidated
reception of the DECT eoc message.
Analog interface selectfor all auto mode configurations
Rx Super frame synchronization. The rising edge of SFSr indicates the
beginning of the received superframe on the line. UID provides this output
only when ESFR bit in CR4 register is to 1 and LT/NT12 or NT/TE
configuration is done.
Line Signal Detect output (default configuration): This pin is an open drain
output which is normally in the high impedance state but pulls low when the
device previously in the power down state receives a wake-up by Tone from
the line. This signal is intended to be usedto wake-up a micro-controller
from a low power idle mode. The LSD output goes back in the high
impedance state when the device is powered up.
Reset input pin with internal pull-up resistor. When pulled low, all registers
of the UID are reset to their default values. UID is configured according to
configuration inputs bias excluding MW input which must be maintained at
the 0 volt. minimum recommended pulse length is 200
μ
s.
Configuration input pin. When pulled low,GCI channel assigneris selected
(channel number defined by inputs S0, S1, S2). When pulled high, UID is
configured by pins CONF1 and CONF2.
