Sure, but if I had to decide how to code a 'sync to MSB' I would do this:
- maximum number of 1 bits consecutive allowed in coding for 1 byte (FF)
- a 0 to invalidate the sequence making an impossible pattern
- a 1 to the MSB of the next byte to indicate valid data
then 'FF' "0" 'CC' it would tell me the first valid byte (CC) after a sync
But they are only suppositions
EDIT: the single "0" can be interpreted as maximum number of consecutive allowed zero on GCR
could be also "00" actual bits, the meaning would not change
