Description
Remote febe select:
When tied to 0 the remote febe is not transferred. When tied to 1 febe is
transparently reported. Seefigure 10.
Analog interface select for all auto mode configurations
Rx Super frame synchronization. The rising edge of SFSr indicatesthe
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 conf.): Thispin 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 used to wake-up a micro-controller from a
low power idle mode. The LSD output goes back inthe 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 configuredaccording 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 CONF1and CONF2.
