Preliminary Data Sheet
Note: In 128 ms mode the DIS-Bit and the FX-Bit are only evaluated in the 16 processed
channels.
UCCMFR[4:0] (Addr.: 61H): UCC Multiframe Alignment, write protected,
Reset value = 00H
UCCMFR[4:0]
UCCFRS[6:0] (Addr.: 62H): Selection of the special UCC Frame FRS,
write protected, Reset value = 00H

’0’: normal operation
Denotes the UCC frame number for the next complete UCC frame
(beginning with bit 7, phase 0, channel 0) after the first detection of
an active SYNCI impulse with the falling edge of SCLKI (UCC frame
alignment is configured by register UCCALIGN). For explanation
see also Figure 25 and Figure 26.
’1’: The UCC frame corresponding to the value in UCCFRS[4:0] is not
’0’: The UCC frame corresponding to the value in UCCFRS[4:0] is
’1’: enables the output of all frames at UCCO and the activation of
the performance of the software and is unpredictable!
handled as the special UCC frame containing global SIDEC
information but as a frame that contains channel individual
information (like the other UCC frames)
handled as the special UCC frame that contains global SIDEC
related (not channel individual) information.
Note: If this setting is configured, the PCM channel that
corresponds to the value in UCCFRS[4:0] can not individually be
controlled directly via UCC and is considered as a PCM channel
containing no payload data. The DIS-Bit and the FX-Bit are not
evaluated for this channel and set inactive. It is the responsibility
of the software to disable the Echo Canceller and Law conversion
function via the channel individual control registers CHCTR* in
order to enable the transparent (64-clear) mode for this channel.
TUCCO for all frames in 128 ms mode even if the number
does not correspond to one of the 16 processed channels.*
