Document Type and Number:
Japanese Patent JP2821552
Kind Code:
B2
Abstract:
A bidirectional data transfer device (= handshake port) for the data interface of two data-exchanging cells (z1, z2) which in each case contain a data source (dq) and a data sink (ds). To buffer the data transfer in time, at least one latch (f1, f2) is used for each data direction. When the transmitter latch f1 is full or the receiver latch (f2) is empty, a backwards cell stop signal (st1) or, respectively, a forward cell stop signal (st2) freezes the data source (dq) or, respectively, the data sink (ds) in its current data state. These cell stop signals (st1, st2) are controlled by additional status signals (v2, e2) from the respective latch (f1, f2).
