Connecting the local bus UPM controller to a DRAM device requires a detailed examination of the timing
diagrams representing the possible memory cycles that must be performed when accessing this device.
This section describes timing diagrams for various UPM configurations for fast-page mode DRAM, with
LCRR[CLKDIV] = 4 (clock ratio of 8) or 8 (clock ratio of 16). These illustrative examples may not
represent the timing necessary for any specific device used with the eLBC. Here, LGPL1 is programmed
to drive R/W of the DRAM, although any LGPLn signal may be used for this purpose.
