Description
0: Select CDR Event counter for reading — events
are counted for a loss of the RXCLK signal, or a loss
of lock
1: Select data event counter
Resets CDR Event count
resets data event counter
enables event counters
Enable counting accumulation of errors
When set, disables 8b10b errors from being counted,
or from affecting the status of the LOCKpin
When set, clears the number of errors in both the
current and previous state of the error count
Select which error count to display
0: Number of errors in current run
1: Number of errors within the selected timing window
Disable exiting NORMAL state when the number of
errors exceeds the error threshold
Error threshold above which the device stops
receiving data and transferring it to the RXOUT pins.
Error threshold above which the device stops
receiving data and transferring it to the RXOUT pins.
