7:0 sync_
These bits select which errors cause a sync request. Sync requests take
request_ena_ link0 priority over the error notification, so if sync request isn’t desired, set
these bits to a ‘0’.
bit7 = multi-frame alignment error
bit6 = frame alignment error
bit5 = link configuration error
bit4 = elastic buffer overflow (bad RBD value)

Lane configuration data for link0. Not used by DAC37J82/DAC38J82
except for lane configuration checking.
These bits select the errors generated are counted in the err_c for the link.
The bits also control what signals are sent out the pad_syncb pin for error
notification.
