Notes:
1. The bidirectional buffers column describes the I/O standards use of a bidirectional signal. The standards labeled as required can
only be used with bidirectional signals and require primitives such as the IOBUF and IOBUFDS.
2. The DCI termination type column describes the type of termination available for the DCI I/O standards. Split refers to the
split-termination resistors.
3. Internal differential termination is always used in bidirectional configuration.
