Bit
Default
Description
-7
0
Reserved
IBLBA_S
6
0
In-band Loopback activate code receive status indication
= 0: No Inband Loopback activate code is detected
= 1: Activate signal is detected and then received over a period of more than t ms, with a bit error rate less than 10-
2. The bit remains set as long as the bit error rate does not exceed 10-2.
Note1:
If automatic remote loopback switching is disabled (ARLP = 0), t = 40 ms.
If automatic remote loopback switching is enabled (ARLP = 1), t= 5.1 s. The rising edge of this bit activates the
remote loopback operation in local end.
Note2:
If IBLBA_IM=0:
A ‘0’ to ‘1’ transition on this bit causes an activate code detected interrupt if IBLBA _IES bit is ‘0’;
Any changes of this bit causes an activate code detected interrupt if IBLBA _IES bit is set to ‘1’.
IBLBD_S
5
0
In-band Loopback deactivate code receive status indication
= 0: No Inband Loopback deactivate signal is detected
= 1: The Inband Loopback deactivate signal is detected and then received over a period of more than t, with a bit
error rate less than 10-2. The bit remains set as long as the bit error rate does not exceed 10-2.
Note1:
If automatic remote loopback switching is disabled (ARLP = 0), t = 40 ms.
If automatic remote loopback switching is enabled (ARLP = 1), t = 5.1 s. The rising edge of this bit disables the
remote loopback operation.
Note2:
If IBLBD_IM=0:
A ‘0’ to ‘1’ transition on this bit causes a deactivate code detected interrupt if IBLBD _IES bit is ‘0’;
Any changes of this bit causes a deactivate code detected interrupt if IBLBD _IES bit is set to ‘1’.
PRBS_S
4
0
Synchronous status indication of PRBS/QRSS (real time)
= 0: 215-1 (E1) PRBS or 220-1 (T1/J1) QRSS not detected
= 1: 215-1 (E1) PRBS or 220-1 (T1/J1) QRSS detected
Note:
If PRBS_IM=0:
A ‘0’ to ‘1’ transition on this bit causes a synchronous status detected interrupt if PRBS _IES bit is ‘0’.
Any changes of this bit causes an interrupt if PRBS_IES bit is set to ‘1’.
TCLK_LOS
3
0
TCLKn loss indication
= 0: Normal
= 1: TCLK pin has not toggled for more than 70 MCLK cycles
Note:
If TCLK_IM=0:
A ‘0’ to ‘1’ transition on this bit causes an interrupt if TCLK _IES bit is ‘0’.
Any changes of this bit causes an interrupt if TCLK_IES bit is set to ‘1’.
