Variable-Latency I/O Parameters and Timing Diagrams
The following sections describe the read/write parameters and timing diagrams for VLIO memory
interfaces with the memory controller.
Table 6-20 lists the timing-information references for both the read and the write timing diagrams.
Note: Table 6-20 lists programmable register items. For more information on these items, see the
“Memory Controller” chapter in the Intel PXA27x Processor Family Developer’s Manual for
register configurations.
