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 Table19-16 on page 19-31. Detailed information

about the operation of individual signals can be found in both Chapter8, “LCD Controller,” and Chapter7,

“DRAM Controller.”
