Function
2.048 Mbit/s UCC highway input. Start of
timeslot 0, bit 7 and frame number can be
flexibly aligned to the SYNCI/SYNCO pulse in
122 ns steps via registers UCCMFR,
UCCALIGN and PHALIGN[7:6]

122 ns steps via registers UCCMFR,
UCCALIGN and PHALIGN[7:6]
Tristate control signal for external tristate
output buffer at the UCCO bus, active low.
Remains inactive after a power on reset until
the configuration by the P has been settled.
Active only at UCC timeslot 0 for UCC frames
that correspond to processed PCM channels
Function
Transmit Signaling Marker, indicating robbed
bits at SI, corresponding to the delay of SI
Transmit Multiframe Begin Input
corresponding to the delay of SI
corresponding to the delay of SO. The delay of
TMFBI to TMFBO is identical to the delay of SI
to SO
