NAME AND DESCRIPTION
Receive Side Signaling Reinsertion Enable. See Section
details.
0 = do not re-insert signaling bits into the data stream presented at the
RSER pin
1 = re-insert the signaling bits into data stream presented at the RSER
pin
Receive Per-Channel Signaling Insert. See Section
details.
0 = do not use RCHBLK to determine which channels should have
signaling re-inserted
1 = use RCHBLK to determine which channels should have signaling
re-inserted
Receive Force Signaling All 1s. See Section
0 = do not force extracted robbed-bit signaling bit positions to a 1
1 = force extracted robbed-bit signaling bit positions to a 1
Receive Freeze Enable. See Section
0 = no freezing of receive signaling data will occur
1 = allow freezing of receive signaling data at RSIG (and RSER if
CCR4.7 = 1).
Receive Force Freeze. Freezes receive side signaling at RSIG (and
RSER if CCR4.7 = 1); will override Receive Freeze Enable (RFE). See
Section
0 = do not force a freeze event
1 = force a freeze event
Transmit Hardware Signaling Insertion Enable. See Section
details.
0 = do not insert signaling from the TSIG pin into the data stream
presented at the TSER pin
1 = insert the signaling from the TSIG pin into data stream presented at
the TSER pin
Transmit Per-Channel Signaling Insert. See Section
0 = do not use TCHBLK to determine which channels should have
signaling inserted from TSIG
1 = use TCHBLK to determine which channels should have signaling
inserted from TSIG
Transmit Idle Registers (TIR) Function Select. See Section
timing 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)
