The latency counter bits determine how many clocks occur between the beginning of a
READ or WRITE operation and the first data value transferred. Only latency code two
(three clocks) or latency code three (four clocks) is allowed (see Table 5 and Figure 21
below).
The operating mode bit selects either synchronous burst operation or the default asyn-
chronous mode of operation.
