... Write Enable 2/Load (WEN2/LD) are ignored when the FIFO is full. The FIFO is configured to have programmable flags when the Write Enable 2/Load (WEN2/LD) is set LOW at Reset (RS=LOW). The IDT72421/72201/ 72211/72221/72231/72241/72251 devices contain four 8-bit offset registers which can be loaded with data on the inputs, or read on the outputs. See Figure 3 for details of the size of the registers and the default values ...
