It is set also after alarm simulation is finished and the receiver is still
synchron. Only active if CRC-multiframe format is selected.
Receive Time Out 400 msec
Only active if multiframing is enabled.
The
FRS0.LFA = 0 and is searching for the multiframing. This interrupt will
be set to indicate that no multiframing could be found within a time
window of 400 msec after basic framing has been achieved. In
multiframe synchronous state this interrupt will not be generated.
Alarm Indication Signal
This bit is set when an alarm indication signal is detected and bit
FRS0.AIS is set. It will be set during alarm simulation.
If GCR.SCI is set high this interrupt status bit will be 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
bitstream and FRS0.LOS is set. It will be set during alarm simulation.
If GCR.SCI is set high this interrupt status bit will be set with every
change of state of FRS0.LOS.
Remote Alarm Recovery
Set if a remote alarm in TS0 is cleared and bit FRS0.RA 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.RA is set. It will
be set during alarm simulation.
