0
This bit determines where the CRC-6 bits should be inserted from.
0 = The CRC-6 bits are generated and inserted internally.
1 = The CRC-6 bits are passed through from the input serial data
only when IOMUX=0 and CSS < 3.
NOTE
:
This bit-field is ignored if CRC Multiframe Alignment is
disabled

Framing Alignment Bits Source Select
Determines where the framing alignment bits should be inserted
from.
0 = The framing alignment bits are inserted internally.
1 = The framing alignment bits are passed through from the input
serial data only when IOMUX=0 and CSS < 3.

0
Specifies if the Sa8 bit-field (bit 7 within timeslot 0 of non-FAS
frames) will be involved in the transport of Data Link Information
0 = Data Link Interface does not use Sa8 bit-field. Sa8 bit-field within
each outbound non-FAS frame will be set to 1.
1 = Data Link Interface uses Sa8 bit-field.

OTE: This bit-field is only active when the TxSIGDL[2:0] bits within
this register are set to 00x. This bit-field is ignored in all other
case.
