DL2_BIT[7:0]:
The data link 2 bit select (DL2_BIT[7:0]) bits controls into which bits of the
time slot/channel data from TDPR #2 are to be inserted. If DL2_BIT[x] is a
logic 1, the data link is inserted into that bit. To insert the data link into the
entire time slot, all eight DL2_BIT[x] bits must be set to a logic 1. DL2_BIT[7]
corresponds to the most significant bit (bit 1, the first bit transmitted) of the
time slot and DL2_BIT[0] corresponds to the least significant bit (bit 8, the last
bit transmitted) of the time slot. The DL2_BIT[7:0] bits have no effect when
the DL2_EVEN and DL2_ODD bits of the TXCI Data Link 2 Control register
are both logic 0.
