or flip-flop is available to implement a synchronous read. In this case, the clock-to-out of
the flip-flop determines the overall delay and improves performance. However, one
additional cycle of clock latency is added. Any of the 32 bits can be read out
asynchronously (at the O6 LUT outputs) by varying the 5-bit address. This capability is
useful in creating smaller shift registers (less than 32 bits). For example, when building a
13-bit shift register, simply set the address to the 13
diagram of a 32-bit shift register.
