WE# Control
Selects the WE# control used for the DRAM. DRAM
uses one of two methods of control when writing to
memory. These methods are referred to as 2-CAS# and
2-WE#.
The S5U13506 evaluation boards use DRAM requiring
the 2-CAS# method.
Refresh Time
Selects the number of ms required to refresh 256 rows
of DRAM.
Suspend Mode Refresh
Selects the DRAM refresh method used during power
save mode.
The S5U13506 evaluation boards use DRAM requiring
CAS before RAS. For all other implementations, refer
to the manufacturer’s specification for DRAM refresh
requirements.
CAS before RAS
This setting is selected for DRAM that requires timing
where the CAS signal occurs just before the RAS
signal.
Self refresh
No refresh
This setting is selected for DRAM that requires no
signal from the S1D1306 to maintain memory refresh.
This setting does not refresh the memory during power
save mode. If this option is selected, the memory
contents are lost during power save.
Installed Memory
Selects the amount of DRAM available for the display
buffer.
The S1D13506 evaluation board use 2M bytes of
DRAM.
