Burst Control Words are either forced through a tx_sopin<N> and tx_bctlin<N>
input, forced through a change of channel on tx_chanin<N>, or implied by the value of BurstMax. The Segmented
LBUS requires that there be only one Burst Control Word per clock cycle. Consequently,
two bursts implied or forced cannot begin in the same clock cycle. The signal stat_tx_burst_err is asserted if two Burst Control Words
occur in the same cycle.
