NOTE:
1. When the common channel signaling mode is enabled (TCR.5 = 1), the TSD input is disabled
internally; all timeslot 16 data is sampled at TSER.

CCR.7
Reserved; must be 0 for proper operation.
TAFP
CCR.6
Transmit Align Frame Position
1
When clear, the CAS multiframe begins with a frame containing
the frame alignment signal. When set, the CAS multiframe begins
with a frame not containing the frame alignment signal.
THDE
CCR.5
Transmit HDB3 Enable
0 = Outgoing data at TPOS and TNEG is AMI coded.
1 = Outgoing data at TPOS and TNEG is HDB3 coded.
RHDE
CCR.4
Receive HDB3 Enable
0 = Incoming data at RPOS and RNEG is AMI coded.
1 = Incoming data is RPOS and RNEG is HDB3 coded.
TCE
CCR.3
Transmit CRC4 Enable
When set, outgoing international bit positions in frames 0 through
12 and 14 are replaced by CRC4 multiframe alignment and
checksum words.
RCE
CCR.2
Receive CRC4 Enable
0 = Disable CRC4 multiframe synchronizer.
1 = Enable CRC4 synchronizer; search for CRC4 multiframe
alignment once frame alignment complete.
SAS
CCR.1
Sync Algorithm Select
0 = Use old DS2181 sync algorithm
1 = Use new DS2181A sync algorithm
LLB
CCR.0
Local Loopback
0 = Normal operation.
1 = Internally loop TPOS, TNEG, and TCLK to RPOS, RNEG,
and RCLK.
NOTES:
1. This bit must be cleared when CRC4 multiframe mode is enabled (CCR.3 = 1); its state does not
affect CCS framing (RCR.5 = 1).
2. CCR is considered a receive register and operates from RCLK and SCLK.
