signal - with respect to PFS. The position of the CFI-frame relative to the
FSC-output signal is not affected by these settings, but is instead determined by
CMD2:FC2..0. If CMD1:CSS = 1, the CFI-frame will be shifted with respect to the
FSC-input signal.
Configurable Interface Bit Number Register (CBNR)
E.g.: If the framing signal is to mark time slot 0 (bit 7), CTAR must be set to
02
CFI-Bit Number 7..0.
The number of bits that constitute a CFI-frame must be programmed to
CMD2, CBNR:CBN9..0 as indicated below.
CBN9..0 = number of bits
For a 8-kHz frame structure, the number of bits per frame can be derived
from the data rate by division with 8000.
Time Slot Number.
The CFI-framing signal (PFS if CMD1:CSS = 0 or FSC if CMD1:CSS = 1)
marks the CFI time slot called TSN according to the following formula:
TSN6..0 = TSN + 2
