19.3.20 Page-Hit CPU Read Cycle in Power-down Mode (CAS
Latency = 1, Bit APEN of SDRAM Power-down
Register = 1)
Figure 19-21 shows the timing diagram for the page-hit CPU read cycle in power-down mode. 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.”
