NCO Synchronization (default: 0x02)
When this bit is set, the NCO phase is initialized on the LMFC/LEMC boundary immediately after the rising edge of the SYNC~ signal (default). This feature works in 8B/10B and 64B/66B modes. This feature can be used to precisely align the NCO phase in several ADCs. In 64B/66B modes SYNC~ is only used for this purpose and does not affect the link operation.
After writing ‘0’ and then ‘1’ to this bit, the next SYSREF rising edge will initialize the NCO phase. Once the NCO phase has been initialized by SYSREF, the NCO will not re-initialize on future SYSREF edges unless ‘0’ and ‘1’ is written to this bit again.
