Abstract
The present invention is generally directed to a method and apparatus for transferring data from an integrated circuit that is capable of bidirectional data communication. In accordance with one aspect of the invention, an apparatus is provided having a circuit for splitting the data into two portions--a high bit portion and a low bit portion. The circuit also includes two data paths. A first data path communicates the high bit portion of the data and a second data path communicates the low bit portion of the data. The apparatus further includes an output circuit that is configured to connect outputs of the first and second data paths to a common, bidirectional data bus. Finally the apparatus includes a hold circuit configured to hold a last data value on the common data bus for at least one clock cycle before allowing circuitry to receive data from the common bus. A method is also provided for transferring data from an integrated circuit capable of bidirectional data communication. The method operates by splitting data into a first group of bits and a second group of bits. The method further includes steps of transmitting the first group of bits along a first data path, and transm…
