Transmit data organization Transmit data spread over outputs, Transmit data independent over outputs, Transmit data spread over outputs with data/Control split
TXD bus width This allows organizing the splitting of the data bus.
TXCTL bus width This allows organizing the splitting of the data bus.
Expose dynamic delay control Disable and Enable. See Table 1.
