DL1_BIT[7:0]:
The data link 1 bit select (DL1_BIT[7:0]) bits controls which bits of the time
slot/channel are to be extracted and passed to RDLC #1. If DL1_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 DL1_BIT[x] bits must be set to a logic 1.
DL1_BIT[7] corresponds to the most significant bit (bit 1, the first bit received)
of the time slot and DL1_BIT[0] corresponds to the least significant bit (bit 8,
the last bit received) of the time slot. The DL1_BIT[7:0] bits have no effect
when the DL1_EVEN and DL1_ODD bits of the RXCE Data Link 1 Control
register are both logic 0.
