DRAM Timing
The DRAM timing is controlled by the DRAM Timing Registers. The
timing type is dependent on the system design. Slower rates may be
required in some system designs to support loose layouts or slower
memory.
SDRAM Cycle Length
This field sets the length of each SDRAM cycle. By default, this field is
set to
3 .
DRAM Read Pipeline
When enabled, this field supports pipelining of DRAM reads.
Sustained 3T Write
This field allows support for PBSRAM sustained 3T writes.
Cache Rd+CPU Wt Pipeline
When enabled, this item allows pipelining of cache reads and CPU
writes.
Cache Timing
This field sets the timing of the cache in the system. The options are fast
and fastest . By default, this field is set to fast .
