TESE
CCR3.7
Transmit Side Elastic Store Enable
0 = elastic store is bypassed
1 = elastic store is enabled
TCBFS
CCR3.6
Transmit Channel Blocking Registers (TCBR) Function
Select
0 = TCBRs define the operation of the TCHBLK output pin
1 = TCBRs define which signaling bits are to be inserted
TIRFS
CCR3.5
Transmit Idle Registers (TIR) Function Select. See Section
15 for details.
0 = TIRs define in which channels to insert idle code
1 = TIRs define in which channels to insert data from RSER
(i.e., Per Channel Loopback function)

CCR3.4
Not Assigned. Should be set to zero when written.
RSRE
CCR3.3
Receive Side Signaling Reinsertion Enable. See Section 14
for details.
0 = do not reinsert signaling bits into the data stream presented
at the RSER pin
1 = reinsert the signaling bits into data stream presented at the
RSER pin
THSE
CCR3.2
Transmit Side Hardware Signaling Insertion Enable. See
Section 14 for details.
0 = do not insert signaling from the TSIG pin into the data
stream presented at the TSER pin
1 = insert signaling from the TSIG pin into the data stream
presented at the TSER pin
TBCS
CCR3.1
