then checking the next 32 data stream bits. Synchronization is achieved if all 32 bits match the incoming pattern. If
at least six incoming bits in the current 64-bit window do not match the receive pattern generator, automatic pattern
resynchronization is initiated. Automatic pattern resynchronization can be disabled.

10.11.4.2 Receive Repetitive Pattern Synchronization
Repetitive pattern synchronization synchronizes the receive pattern generator to the incoming repetitive pattern.
The receive pattern generator is synchronized by searching each incoming data stream bit position for the
repetitive pattern, and then checking the next 32 data stream bits. Synchronization is achieved if all 32 bits match
the incoming pattern. If at least six incoming bits in the current 64-bit window do not match the receive PRBS
pattern generator, automatic pattern resynchronization is initiated. Automatic pattern resynchronization can be
disabled.
