The device provides synchronous data exchange between the two ports. Data is stored in the internal registers on the low-to-high transition of the clock (CLK) input when the appropriate CLKEN inputs are low. The select (SEL) line selects 1B or 2B data for the A outputs. For data transfer in the A-to-B direction, a two stage pipeline is provided in the A-to1B path,with a single storage register in the A-to-2B path. Proper control of the CLKENA inputs allows two sequential 12-bit words to be presented synchronously as a 24-bit on the B port. Data flow is controlled by the active-low output enables (OEA, OEB). The control terminals are registered to synchronize the bus direction changes with the CLK. |
