14.1
Read Mode (RCR[15])
All partitions support two high-performance read configurations: synchronous burst mode and
asynchronous page mode (default). RCR[15] sets the read configuration to one of these modes.
Status register, query, and identifier modes support only asynchronous and single-synchronous read
operations.
14.2
First Access Latency Count (RCR[13:11])
The First Access Latency Count (RCR[13:11]) configuration tells the device how many clocks
must elapse from ADV# de-assertion (VIH) before the first data word should be driven onto its data
pins. The input clock frequency determines this value. See Table 28, “Read Configuration Register
Descriptions” on page 84 for latency values. Figure 36 shows data output latency from ADV#
assertion for different latencies. Refer to Section 14.2.1, “Latency Count Settings” on page 87 for
Latency Code Settings.
Note:
Other First Access Latency Configuration settings are reserved.
