Starting Column
1. Internal READ and WRITE operations start at the same point in time for BC4 as they do for
2. Z = Data and strobe output drivers are in tristate.
3. V = A valid logic level (0 or 1), but the respective input buffer ignores level-on input pins.
4. X = “Don’t Care.”
DLL RESET is defined by MR0[8] (see Figure 54 on page 110). Programming MR0[8] to
“1” activates the DLL RESET function. MR0[8] is self-clearing, meaning it returns to a
value of “0” after the DLL RESET function has been initiated.
Anytime the DLL RESET function is initiated, CKE must be HIGH and the clock held
stable for 512 (
allow time for the internal clock to be synchronized with the external clock. Failing to
wait for synchronization to occur may result in invalid output timing specifications,
such as
WRITE recovery time is defined by MR0[11:9] (see Figure 54 on page 110). Write recovery
values of 5, 6, 7, 8, 10, or 12 may be used by programming MR0[11:9]. The user is
required to program the correct value of write recovery and is calculated by dividing
