This bit is set when the conditions defined via bit GCR.AIS3 are detected. The flag stays
active for at least one multiframe. It will be reset with the beginning of the next following
multiframe if no alarm condition is detected.
The bit will be set during alarm simulation and reset if ASR.SC = 0, 3, 4, 7 and no alarm
condition exists.
The flag is set if pulseframe synchronization has been lost. The conditions are specified via
bit RC1.SLC.
The flag is cleared when synchronization has been regained.
The flag is set after detecting remote alarm. Conditions for setting/resetting are defined by
bit RC1.RRAM.
The bit will be set during alarm simulation and reset if ASR.SC = 0, 3, 4, 7 and no alarm
condition exists.
Set after a slip caused a received frame to be repeated. The bit indicates that the receive
route clock frequency is low relative to the internal clock. The bit will be cleared by bit
CCR.CLR. It will be set during alarm simulation.
Set after a slip caused a received frame to be discarded. The bit indicates that the receive
route clock frequency is high relative to the internal clock. The bit will be cleared by bit
CCR.CLR. It will be set during alarm simulation.
Toggles when no framing candidate (pulseframing or multiframing) is found and a new
frame search is started.
