Multiframe Force Resynchronization
Only
(FMR2.RFS(1:0) = 10).
A transition from low to high initiates the resynchronization procedure
for CRC-multiframe alignment without influencing doubleframe
synchronous state. In case, “Automatic Force Resynchronization”
(FMR1.AFR) is enabled and multiframe alignment cannot be
regained, a new search of doubleframe (and CRC multiframe) is
automatically initiated.
Automatic Force Resynchronization
Only
(FMR2.RFS(1:0) = 10).
If this bit is set, a search of doubleframe alignment is automatically
initiated if two multiframe patterns with a distance of n
not been found within a time interval of 8 ms after doubleframe
alignment has been regained or command FMR1.MFCS has been
issued.
