and internally connected to tdint_clk if a single clock domain is
selected. Signals prefixed with aN_ are synchronous to this clock.
Atlantic data available (one for each Atlantic interface). Asserted when
the Atlantic FIFO buffer has at least ctl_atx_fth bytes of free space
available.
Atlantic enable (one for each Atlantic interface).
Atlantic data bus (one for each Atlantic interface). The width is set by
the Atlantic interface width parameter.

invalid octets on the lower bits of aN_atxdat . Valid only when
aN_atxeop is asserted, must be zero otherwise. The width is
log2(Atlantic interface width/8) .
Atlantic Error (one for each Atlantic interface). Translates to an EOP-
Abort on the transmit data bus.
Atlantic port address. Only present when you turn on turn on Shared
Buffer with Embedded Addressing .
Note to Table 5–5 :
(1) N is equal to the number of ports for the individual buffers mode; N is equal to zero when you turn on Shared Buffer with Embedded
Addressing .
