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:
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 and IBLBA_IES=0, a ‘0’ to ‘1’ transition on this bit will cause an activate code detect interrupt.
If IBLBA_IM=0 and IBLBA_IES=1, any changes on this bit will cause an activate code detect interrupt.
= 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
Note1:
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 and IBLBD_IES=0, a ‘0’ to ‘1’ transition on this bit will cause a deactivate code detect interrupt.
If IBLBD_IM=0 and IBLBD_IES=1, any changes on this bit will cause a deactivate code detect interrupt.
= 0: 2
= 1: 2
Note:
If PRBS_IM=0 and PRBS_IES=0, a ‘0’ to ‘1’ transition on this bit will cause a synchronous status detect interrupt.
If PRBS_IM=0 and PRBS_IES=1, any changes on this bit will cause a synchronous status detect interrupt.
TCLKn loss indication
= 0: normal
= 1: TCLKn pin has not toggled for more than 70 MCLK cycles.
Note:
If TCLK_IM=0 and TCLK_IES=0, a ‘0’ to ‘1’ transition on this bit will cause an interrupt.
If TCLK_IM=0 and TCLK_IES=1, any changes on this bit will cause an interrupt.
Line driver status indication
= 0: normal operation
= 1: line driver short circuit is detected.
Note:
If DF_IM=0 and DF_IES=0, a ‘0’ to ‘1’ transition on this bit will cause an interrupt.
If DF_IM=0 and DF_IES=1, any changes on this bit will cause an interrupt.
