CCB Input Data Format
Caution: The bits labeled with an asterisk must be set to 0.
(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.
No. 6488-7/14
