Figure 4. Synchronous/Asynchronous State Diagram
Read Mode Setting
On power-up or hardware reset, the device is set to be in asynchronous read mode. This setting
allows the system to enable or disable burst mode during system operations. Address A19 deter-
mines this setting: “1” for asynchronous mode, “0” for synchronous mode.
Programmable Wait State Configuration
The programmable wait state feature informs the device of the number of clock cycles that must
elapse after AVD# is driven active before data will be available. This value is determined by the
input frequency of the device. Address bits A14–A12 determine the setting (see Table 14, “Pro-
The wait state command sequence instructs the device to set a particular number of clock cycles
for the initial access in burst mode. The number of wait states that should be programmed into
the device is directly related to the clock frequency.
