Auto Configuration
The default setting of the optimal timings for items 3 through 7 for 60ns EDO DRAM
modules.
EDO DRAM Speed Selection
This item set the EDO DRAM Read/Write timings that the system uses. When item
of "Auto Configuration" is disabled, this item will not show up.
EDO CASx# MA Wait State
The board designer may elect to insert one additional wait state before the assertion
of the first CASx# for page hit cycles, thus allowing one additional clock of MA
setup time to the CASx# for the leadoff page hit cycle. Do not change from the
manufacturer's default unless you are getting memory addressing errors.
EDO RASx# Wait State
The board designer may elect to insert one additional wait state before RASx# is
asserted for row misses, thus allowing one additional MAX [13:0] setup time to
RASx# assertion. This field applies only if EDO DRAM is installed in the system.
SDRAM RAS-to-CAS Delay
This field lets you control the number of DCLKs between a Row Activate command
and a read or write command.
SDRAM RAS Precharge Time
The precharge time is the number of cycles it takes for the RAS to accumulate its
charge before DRAM refresh. If insufficient time is allowed, refresh may be incom-
plete and the DRAM may fail to retain data. This field applies only if synchronous
DRAM is installed in the system.
