NAME
DESCRIPTION
PCS TX_RX Enable
1 = Enables 1000Base-X PCS Tx and PCS Rx functions
0 = Disables 1000Base-X PCS Tx and PCS Rx functions (Default 1’b0)
Encode Decode Enable
0 = 8B/10B encode decode functions are disabled (Default 1’b0)
1 = 8B/10B encode decode functions are enabled
TX Edge Mode
When channel is in DDR mode
1 = Source aligned timing on transmit parallel interface.
0 = Source centered timing on transmit parallel interface. Data is latched on both
rising and falling clock edges.
When channel is in SDR mode
1 = Rising edge align mode. Incoming parallel data is aligned to rising edge of
parallel input clock. Internally data is latched at the falling edge of the clock.
0 = Falling edge align mode. Incoming data is aligned to falling edge of parallel
input clock. Internally data is latched at the rising edge of the clock
RX Edge Mode
When channel is in DDR mode
1 = Source aligned timing on receive parallel interface. Data changes at clock
edge.
0 = Source centered timing on receive parallel interface.
When channel is in SDR mode
1 = Rising edge align mode. Outgoing parallel data is aligned to the rising edge of
the parallel output clock
0 = Falling edge align mode. Outgoing parallel data is aligned to the falling edge of
the parallel output clock

DESCRIPTION
Test Pattern Sync
When high indicates alignment has been determined and a correct pattern has been
received for fixed test patterns.
CRPAT Sync
When high indicates alignment has been determined and a correct pattern has been
received for continuous test patterns.
