User Selectable Quad / Dual Mode - Choose between two or

four independent FIFOs

Quad Mode offers

- Eight discrete clock domain, (four write clocks & four read clocks)

- Four separate write ports, write data to four independent FIFOs

- 10-bit wide write ports

- Four separate read ports, read data from any of four independent FIFOs

- Independent set of status flags and control signals for each FIFO

Dual Mode offers

- Four discrete clock domain, (two write clocks & two read clocks)

- Two separate write ports, write data to two independent FIFOs

- 10-bit/20-bit wide write ports

- Two separate read ports, read data from any of two independent FIFOs

- Independent set of status flags and control signals for each FIFO

- Bus-Matching on read and write port x10/x20

- Maximum depth of each FIFO is the same as in Quad Mode
