The CAS latency is the delay, in clock cycles, between the registration of a READ
command and the availability of the first piece of output data. The latency can be set to
1, 2, or 3 clocks.
If a READ command is registered at clock edge n, and the latency is m clocks, the data
will be available by clock edge n + m. The DQs will start driving as a result of the clock
edge one cycle earlier (n + m - 1), and provided that the relevant access times are met,
the data will be valid by clock edge n + m. For example, assuming that the clock cycle
time is such that all relevant access times are met, if a READ command is registered at T0
and the latency is programmed to 2 clocks, the DQs will start driving after T1 and the
data will be valid by T2, as shown in Figure 5 on page 15. Table 6 on page 15 indicates the
operating frequencies at which each CAS latency setting can be used.
Reserved states should not be used because unknown operation or incompatibility with
future versions may result.
