Description
DRAM/Continuous Synchronous DRAM Space
Select
These bits designate DRAM/continuous
synchronous DRAM space for areas 2 to 5.
When continuous DRAM space is set, it is possible
to connect large-capacity DRAM exceeding 2
Mbytes per area. In this case, the RAS signal is
output from the CS2 pin.
When continuous synchronous DRAM space is set,
it is possible to connect large-capacity synchronous
DRAM exceeding 2 Mbytes per area. In this case,
the RAS, CAS, and WE signals are output from
CS2, CS3, and CS4 pins, respectively. When
synchronous DRAM mode is set, the mode
registers of the synchronous DRAM can be set.
000: Normal space
001: Normal space in areas 3 to 5
010: Normal space in areas 4 and 5

111: Continuous DRAM space in areas 2 to 5
Burst Access Enable
Selects enabling or disabling of burst access to
areas designated as DRAM/continuous
synchronous DRAM space. DRAM/continuous
synchronous DRAM space burst access is
performed in fast page mode. When using EDO
page mode DRAM, the OE signal must be
connected.
