Interleaved mode is when packets with different channel addresses/identifiers are burst interleaved. Ensure that the following are strictly observed:

  • When tx_sopin<N> has been asserted for a channel, it cannot be asserted again for that channel until a corresponding tx_eopin<N> for that channel has been written.
  • Unless tx_eopin<N> is asserted, the full width of the segment, tx_datain<N> must contain valid data as discussed in TX LBUS Interface.

The size of the bursts generated in interleaved mode is governed by the tx_bctlin<N> inputs (see Use of TX_BCTLIN), CTL_TX_BURSTSHORT, CTL_TX_BURSTMAX, and the changing of the channel ID of packets.

Important: AMD requires implementing the Optional Scheduling Enhancement as described in section 5.3.2.1.1 of the Interlaken Protocol Definition, Revision 1.2, October 7, 2008.
