The CAS latency (CL) is the delay, in clock cycles, between the registration of a READ
command and the availability of the first output data. The latency can be set to 2 or 3
clocks, as shown in Figure 18 (page 52).
For CL = 3, if the READ command is registered at clock edge n, then the data will be
nominally available at (n + 2 clocks +
tered at clock edge n, then the data will be nominally available at (n + 1 clock +
