Read Mode

The Read Mode (RM) bit selects synchronous burst-mode or asynchronous page-mode

operation for the device. When the RM bit is set, asynchronous page mode is selected

(default). When RM is cleared, synchronous burst mode is selected.

Latency Count

The Latency Count (LC) bits tell the device how many clock cycles must elapse from the

rising edge of ADV# (or from the first valid clock edge after ADV# is asserted) until the

first valid data word is to be driven onto DQ[15:0]. The input clock frequency is used to

determine this value and Figure 26 shows the data output latency for the different

settings of LC. The maximum Latency Count for P30 would be Code 4 based on the Max

Clock frequency specification of 52 mhz, and there will be zero WAIT States when

bursting within the word line. Please also refer to “End of Word Line (EOWL)

Considerations” on page 55 for more information on EOWL.

Refer to Table 26, “Latency Count (LC) and Frequency Support” on page 51 for Latency

Code Settings.
