Page-Hit CPU Byte-Write Cycle for 8-Bit SDRAM (CAS
Latency = 1)
Latency = 1)
Figure 19-20 shows the timing diagram for the page-hit SDRAM CPU byte-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.”
