Page-Miss SDRAM CPU Write Cycle (CAS
Latency = 1)
Figure 19-18 shows the timing diagram for the page-miss SDRAM CPU write 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.”
