Signal Direction Width Description
avalon_st_rx_
empty[]
Out 2/3
Contains the number of empty bytes during the
cycle that contain the end of the RX data.
The width is 3 bits when you enable the Use 64-bit
Ethernet 10G MAC Avalon Streaming Interface
option. Otherwise, it is 2 bits.

Signal Direction Width Description
avalon_st_pause_
data[]
In 2 Set this signal to the following values to trigger the
corresponding actions.
• 0x0: Stops pause frame generation.
• 0x1: Generates an XON pause frame.
• 0x2: Generates an XOFF pause frame. The MAC IP
core sets the pause quanta field in the pause frame to
the value in the tx_pauseframe_quanta register.
• 0x3: Reserved.
Note: This signal only takes effect if tx_
pauseframe_enable[2:1] is 00 (default)
avalon_st_tx_pause_
length_valid
In 1 This signal is present in the MAC TX only variation.
Assert this signal to request the MAC IP core to suspend
data transmission. When you assert this signal, ensure
that a valid pause quanta is available on the avalon_st_
tx_pause_length_data bus.
avalon_st_tx_pause_
length_data[]
In 16 This signal is present only in the MAC TX only
variation.
Use this bus to specify the pause quanta in unit of
quanta, where 1 unit = 512 bits time.
