Enables the sync word detection:
0  OFF
1  ON
FIFO filling condition:
0  If SyncAddress interrupt occurs
1  As long as FifoFillCondition is set
Size of the sync word:
(SyncSize + 1) bytes
Number of tolerated bit errors in sync word
First byte of sync word (MSB byte)
Used if SyncOn is set.
Second byte of sync word
Used if SyncOn is set and (SyncSize +1) >= 2.
Third byte of sync word.
Used if SyncOn is set and (SyncSize +1) >= 3.
Forth byte of sync word.
Used if SyncOn is set and (SyncSize +1) >= 4.
Fifth byte of sync word.
Used if SyncOn is set and (SyncSize +1) >= 5.
Sixth byte of sync word.
Used if SyncOn is set and (SyncSize +1) >= 6.
Seventh byte of sync word.
Used if SyncOn is set and (SyncSize +1) >= 7.
Eighth byte of sync word.
Used if SyncOn is set and (SyncSize +1) = 8.
