... FIFO2 is less than or equal to the value in the Almost Full B offset [1] register, Y2. During Master Reset. A HIGH on FWFT selects CY Standard mode, a LOW selects First -Word Fall-Through mode. Once the timing mode has been selected, the level on FWFT/STAN must be static throughout device operation. CY7C43642AV CY7C43662AV CY7C43682AV [1] Page ...

... Port B output register to all zeroes. A LOW pulse on MRST1 selects the programming method (serial or parallel) and one of three programmable flag default offsets for FIFO1. Four LOW-to-HIGH transitions of CLKA and four LOW-to-HIGH transitions of CLKB must occur while MRST1 is LOW. CY7C43642AV CY7C43662AV CY7C43682AV outputs available 0– ...
