Number of continuous good code groups received to reduce the error count by one.
Synchronization State Machine
In Serial RapidIO mode, the ALTGX MegaWizard Plug-In Manager defaults the word
alignment pattern to K28.5. The word aligner has a synchronization state machine that
handles the receiver lane synchronization.
The ALTGX MegaWizard Plug-In Manager automatically defaults the
synchronization state machine to indicate synchronization when the receiver receives
127 K28.5 (10'b0101111100 or 10'b1010000011) synchronization code groups without
receiving an intermediate invalid code group. After synchronization, the state
machine indicates loss of synchronization when it detects three invalid code groups
separated by less than 255 valid code groups or when it is reset.
Receiver synchronization is indicated on the rx_syncstatus port of each channel. A
high on the rx_syncstatus port indicates that the lane is synchronized and a low
indicates that it has fallen out of synchronization.
