Abstract
A method and apparatus are provided for bidirectionally transmitting a plurality of data values between a first processor and a second processor. Each data value represents a respective plurality of data bits. A direction indicating signal is formed and transmitted from the first processor to the second processor. The direction indicating signal enables the second processor to transfer data to the first processor when the direction indicating signal is in a first state. The direction indicating signal notifies the second processor that the first processor is ready to transfer data to the second processor when the direction indicating signal is in a second state. A clock signal is formed and transmitted from the first processor to the second processor. The clock signal is asynchronously changed from a first state to a second state when each respective one of the plurality of data values is transferred. The data values are transmitted between the processors in a direction indicated by the direction indicating signal. The clock signal is reset to the first state after each respective data signal is transferred.
