Indicating the auto remote loop back status
= 0: The remote loop is inactive. If enabled auto remote loop back by setting bit ARLP, the remote loop is switched
off automatically upon detection of the in-band loop deactivate code for at least 5.1 s, according to ANSI T1. 403
requirements.
=1: The remote loop is active (closed). If enabled by bit ARLP, the remote loop is switched on automatically upon
detection of the in-band loop activate code for at least 5.1 s.
Inband Loopback activate code receive status indication
= 0: no Inband Loopback activate code is detected
= 1: activate code has been detected for more than t ms. Even there is bit error, this bit remains set as long as the
bit error rate is less than 10
Note1:
If automatic remote loop switching is disabled (ARLP = 0), t = 40 ms If automatic remote loop switching is enabled
(ARLP = 1), t= 5.1s. The rising edge of this bit actives the remote loop operation in local end.
Note2:
If NLPA_IE=1, 0 to 1 transition on this bit causes an activate code detected interrupt if NLPA _IES bit is 0; Any
change of this bit causes an activate code detected interrupt if NLPA _IES bit is set to 1.
Inband Loopback deactivate code receive status indication
= 0: no Inband Loopback deactivate code is detected
= 1: the Inband Loopback deactivate code has been detected for more than t. Even there is a bit error, this bit
remains set as long as the bit error rate is less than 10
Note 1:
If automatic remote loop switching is disabled (ARLP = 0), t = 40 ms.If automatic remote loop switching is enabled
(ARLP = 1), t= 5.1s. The rising edge of this bit disables the remote loop back operation.
Note2:
If NLPD_IE=1, a 0 to 1 transition on this bit causes a deactivate code detected interrupt if NLPD _IES bit is 0
Any change of this bit causes a deactivate code detected interrupt if NLPD _IES bit is set to 1.
Synchronous status indication of PRBS/QRSS (real time)
= 0: 2
= 1: 2
Note:
If PRBS_IE=1, 0 to 1 transition on this bit causes an Synchronous status detected interrupt if PRBS _IES bit is 0
Any change of this bit causes an interrupt if PRBS_IES bit is set to 1.
TCLKn loss indication
= 0: normal
= 1: TCLKn pin has not toggled for more than 70 MCLK cycles.
Note:
If TCLK_LOS_IE=1, 0 to 1 transition on this bit causes an interrupt if TCLK _IES bit is 0
Any change of this bit causes an interrupt if TCLK_IES bit is set to 1.
