NOTE
−
Only those signals requiring termination are listed in this table. If a signal is not listed, series
termination is not required for operation in an Ultra DMA mode. Shows signals also requiring a pull-up or
pull-down resistor at the host. The actual termination values should be selected to compensate for transceiver
and trace impedance to match the characteristic cable impedance.
