Description
Column Address Output Cycle Number Select
Selects whether the column address output
cycle in DRAM access comprises 3 states or 2
states. The setting of this bit applies to all areas
designated as DRAM space.
0: 2 states
1: 3 states
Reserved
This bit can be read from or written to.
However, the write value should always be 0.
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
