CKE Assertion
Description
During hardware DDR2 device initialization, the processor does not provide a running MEMCLK for
the specified minimum time of 200 microseconds before CKE is asserted.
Potential Effect on System
No adverse effects have been observed. The processor does not initiate a DRAM access for over
200 microseconds from the start of MEMCLK and the assertion of CKE. If a DDR2 DIMM is
sensitive to this issue, the system may fail to boot.
Suggested Workaround
None required.
Fix Planned
Yes
