DL3_BIT[7:0]:
The data link 3 bit select (DL3_BIT[7:0]) bits controls which bits of the time
slot/channel are to be extracted and passed to RDLC #3. If DL3_BIT[x] is a
logic 1, that bit is extracted as part of the data link. To extract the data link
from the entire time slot, all eight DL3_BIT[x] bits must be set to a logic 1.
DL3_BIT[7] corresponds to the most significant bit (bit 1, the first bit received)
of the time slot and DL3_BIT[0] corresponds to the least significant bit (bit 8,
the last bit received) of the time slot. The DL3_BIT[7:0] bits have no effect
when the DL3_EVEN and DL3_ODD bits of the RXCE Data Link 3 Control
register are both logic 0.
