This item defines the Data-in to PRE command period.
The choice: 1T, 2T
VCM REF To ACT/REF Delay
This item defines VCM REF to REF/ACT command period.
The choice: 10T, 9T.
VCM ACCT To ACT/REF Delay
This item defines VCM ACT to ACT/REF command period.
The choice: 10T, 9T, 8T, Reserved.
Early CKE Delay 1T Control
This option is used when the system operates under low frequency and CKE
delay adjustment method defined in the 'Early CKE Delay Adjustment' which can
not meet setup time and hold time requirement.
The choice: Normal, Delay 1T.
Early CKE Delay Adjust
This item controls the timing for CKE. Various delay options are provided to
ensure that CKE can meet SDRAM setup time and hold time specification when
CKE is driven out.
The Choice: 1ns, 2ns, 3ns, 4ns, 5ns, 6ns, 7ns, 8ns.
Mem. Command Output Time
This item is to control the timing to drive memory command onto the memory bus.
The choice: Normal, Delay 1T.
SDRAM/VCM CAS Latency
When synchronous DRAM is installed, the number of clock cycles of CAS latency
depends on the DRAM timing.
