Description
rx_std_pcfifo_empty[<n>-
1:0]
Output Yes RX phase compensation FIFO status
empty flag.
tx_std_pcfifo_full[<n>-
1:0]
Output Yes TX phase compensation FIFO status full
flag.
tx_std_pcfifo_empty[<n>-
1:0]
Output Yes TX phase compensation FIFO status
empty flag.
Byte Ordering
rx_std_byteorder_ena[<n>-
1:0]
Input No Byte ordering enable. When this signal is
asserted, the byte ordering block initiates a
byte ordering operation if the Byte
ordering control mode is set to manual.
Once byte ordering has occurred, you
must deassert and reassert this signal to
perform another byte ordering operation.
This signal is an synchronous input signal;
however, it must be asserted for at least 1
cycle of rx_std_clkout.
rx_std_byteorder_flag[<n>
-1:0]
Output Yes Byte ordering status flag. When asserted,
indicates that the byte ordering block has
performed a byte order operation. This
signal is asserted on the clock cycle in
which byte ordering occurred. This signal
is synchronous to the rx_std_clkout
clock. You must a synchronizer this signal.
Byte Serializer and Deserializer
rx_std_byterev_ena[<n>-
1:0]
Input No This control signal is available in when the
PMA width is 16 or 20 bits. When
asserted, enables byte reversal on the RX
interface.
