CAS Latency
Note:
The CL is the delay, in clock cycles, between the registration of a READ command and
the availability of the first bit of output data. The latency can be set to 2, 2.5, or 3 (-5B
only) clocks, as shown in Figure 24. Reserved states should not be used, as unknown
operation or incompatibility with future versions may result.
If a READ command is registered at clock edge n, and the latency is m clocks, the data
will be available nominally coincident with clock edge n + m. Table 35 on page 58 indi-
cates the operating frequencies at which each CL setting can be used.
