Fifo full and fifo empty

Webzero, the FIFO is empty and the empty flag is asserted. If the difference between the two values is equal to the depth of the part, the FIFO is full and the full flag is asserted. Other flags, such as half-full, programmable almost-empty and programmable almost-full flags, are generated by the same means.
