The flag is cleared when synchronization has been regained.
Additionally interrupt status ISR2.FAR is set with clearing this bit.
Receive Remote Alarm (Yellow Alarm)
The flag is set after detecting remote alarm (yellow alarm). Conditions
for setting/resetting are defined by bit RC0.RRAM.
With the rising edge of this bit an interrupt status bit ISR2.RA will be
set.
With the falling edge of this bit an interrupt status bit ISR2.RAR will be
set.
The bit will be set during alarm simulation and reset if FRS2.ESC = 0,
3, 4,5,7 and no alarm condition exists.
Loss Of Multiframe Alignment
Set in F12 or F72 format when 2 out of 4- (or 5 or 6) multiframe
alignment patterns are incorrect.
Additionally the interrupt status bit ISR2.LMFA is set.
Cleared after multiframe synchronization has been regained. With the
falling edge of this bit an interrupt status bit ISR2.MFAR is generated.
Frame Search Restart Flag
Toggles when no framing candidate (pulseframing or multiframing) is
found and a new frame search is started.
