File Size : 116 KB Manufacturer:MAXIM Description:each port are independent of one another and can be asynchronous or coincident. The enables for each port are arranged to provide a simple bidirectional interface between microprocessors and/or buses with synchro- nous control. Communication between each port may bypass the FIFO via two mailbox registers. The mailbox registers' width matches the selected Port B bus width. Each mailbox register has a flag (MBF1 and MBF2) to signal when new mail has been stored. Two kinds of reset are available on these FIFOs: Reset and Partial Reset. Reset initializes the read and write pointers to the first location of the memory array and selects serial flag programming, parallel flag programming, or one of three possible default flag offset settings, 8, 16 or 64. Partial Reset also sets the read and write pointers to the first location of the memory. Unlike Reset, any settings existing prior to Partial Reset (i.e., programming method and partial flag default offsets) are retained. Partial Reset is useful since it permits flushing of the FIFO memory without changing any configuration settings. These devices have two modes of operation: In the IDT Standard mode, the first word written to an empty FIFO is deposited into the memory array. A read operation is required to access that word (along with all other words residing in memory). In the First Word Fall Through mode (FWFT), the first word written to an empty FIFO appears automatically on the outputs, no read operation required (Nevertheless, accessing subsequent words does neces- sitate a formal read request). The state of the BE/FWFT pin during Reset determines the mode in use. The FIFO has a combined Empty/Output Ready Flag (EF/OR ) and a combined Full/Input Ready Flag (FF/IR). The EF and FF functions are selected in the IDT Standard mode. EF indicates whether or not the FIFO memory is empty. FF shows whether the memory is full or not. The IR and OR functions
