The purpose of the segmented LBUS is to provide a means to optimally use the data bus. Therefore, as discussed in Active Segments, segments must be filled in sequence with no gaps between used segments. However, if a segment has an EOP, the following segments might be inactive. For example, the following are permitted during a single clock cycle:

  • tx_enain0 = 1 tx_eopin0 = 0 tx_enain1 = 1 tx_eopin1 = 0
  • tx_enain2 = 1 tx_eopin2 = 1 tx_enain3 = 0 tx_eopin3 = 0
  • or
  • tx_enain0 = 1 tx_eopin0 = 0 tx_enain1 = 1 tx_eopin1 = 1
  • tx_enain2 = 0 tx_eopin2 = 0 tx_enain3 = 0 tx_eopin3 = 0
  • or
  • tx_enain0 = 1 tx_eopin0 = 1 tx_enain1 = 0 tx_eopin1 = 0
  • tx_enain2 = 0 tx_eopin2 = 0 tx_enain3 = 0 tx_eopin3 = 0
