19.3.14 Page-Miss SDRAM CPU Read Cycle (CAS
Latency = 1)
Figure 19-15 shows the timing diagram for the page-miss SDRAM CPU read cycle. 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.”
