19.3.25 Page-Hit LCD DMA Cycle for SDRAM (CAS
Latency = 1)
Figure 19-26 shows the timing diagram for the page-hit LCD DMA cycle for 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.”
