This counter contains the number of formatter frames since the last synchronization packet of
128 bits. It is a 12-bit counter with a maximum count value of 4096. This equates to
synchronization every 65536 bytes, that is, 4096 packets x 16 bytes per packet. The default
is set up for a synchronization packet every 1024 bytes, that is, every 64 formatter frames. If
the formatter is configured for continuous mode, full and half-word sync frames are inserted
during normal operation. Under these circumstances, the count value is the maximum
number of complete frames between full synchronization packets.
