Page-Hit CPU Read Cycle for 8-Bit SDRAM (CAS

Latency = 1)

Figure 19-17 shows the timing diagram for the page-hit CPU read cycle for 8-bit SDRAM. The signal
values and units of measure for this figure are found in Table 19-16 on page 19-31. Detailed information
about the operation of individual signals can be found in both Chapter 8, “LCD Controller,” and Chapter 7,
“DRAM Controller.”
