Hardware Description
Receive Time Out 400 ms
Only active if multiframing is enabled.
The
FRS0.LFA = 0 and is searching for the multiframing. This interrupt is
set to indicate that no multiframing was found within a time window of
400 ms after basic framing has been achieved. In multiframe
synchronous state this interrupt is not generated.
Alarm Indication Signal
This bit is set when an alarm indication signal is detected and bit
FRS0.AIS is set. It is set during alarm simulation.
If GCR.SCI is set high this interrupt status bit is set with every change
of state of FRS0.AIS.
Loss-of-Signal
This bit is set when a loss-of-signal alarm is detected in the received
bit stream and FRS0.LOS is set. It is set during alarm simulation.
If GCR.SCI is set high this interrupt status bit is set with every change
of state of FRS0.LOS.
Remote Alarm Recovery
Set if a remote alarm in TS0 is cleared and bit FRS0.RRA is reset. It
is set also after alarm simulation is finished and no remote alarm is
detected.
Remote Alarm
Set if a remote alarm in TS0 is detected and bit FRS0.RRA is set. It
is set during alarm simulation.
