1. Synchronization protection (forward protection) method setting (4 bits): FS0 to FS3
FS3 = 0: If offset words in the correct order could not be detected continuously during the number of blocks specified
by FS0 to FS2, take that to be a lost synchronization state.
FS3 = 1: If blocks with uncorrectable errors were received consecutively during the number of blocks specified by
FS0 to FS2, take that to be a lost synchronization state.
FFF
SSS
012
Condition for detecting lost synchronization
0 0 0 If 3 consecutive blocks matching the FS3 condition are received.
1 0 0 If 4 consecutive blocks matching the FS3 condition are received.
0 1 0 If 5 consecutive blocks matching the FS3 condition are received.
1 1 0 If 6 consecutive blocks matching the FS3 condition are received.
0 0 1 If 8 consecutive blocks matching the FS3 condition are received.
1 0 1 If 10 consecutive blocks matching the FS3 condition are received.
0 1 1 If 12 consecutive blocks matching the FS3 condition are received.
1 1 1 If 16 consecutive blocks matching the FS3 condition are received.
Initial value: FS0 = 0, FS1 = 1, FS2 = 0, FS3 = 0
2. Synchronization detection method setting (1 bit): BS
BS
Synchronization detection conditions
0 If, during 3 blocks, 2 blocks of offset words were detected in the correct order.
1 If the offset words were detected in the correct order in 2 consecutive blocks.
Initial value: BS = 0
