This configuration bit enables (by default) that
all the ranks are refreshed in a staggered/atomic
fashion. If set, the ranks are refreshed in an
independent fashion.
Refresh Enable (REFEN):
Refresh is enabled.
Enabled
DDR Initialization Done (INITDONE):
Indicates that DDR initialization is complete.
DRAM Refresh Hysterisis
(REFHYSTERISIS):
Hysterisis level - Useful for dref_high watermark
cases. The dref_high flag is set when the
dref_high watermark level is exceeded, and is
cleared when the refresh count is less than the
hysterisis level. This bit should be set to a value
less than the high watermark level.

DRAM Refresh Panic Watermark
(REFPANICWM):
When the refresh count exceeds this level, a
refresh request is launched to the scheduler and
the dref_panic flag is set.
10: 7
DRAM Refresh High Watermark
(REFHIGHWM):
When the refresh count exceeds this level, a
refresh request is launched to the scheduler and
the dref_high flag is set.
10: 5
DRAM Refresh Low Watermark
(REFLOWWM):
When the refresh count exceeds this level, a
refresh request is launched to the scheduler and
the dref_low flag is set.
10: 3
Refresh Counter Time Out Value
(REFTIMEOUT):
Program this field with a value that will provide
7.8 us at MCLK frequency.
At various MCLK freq's this results in the
following values:
266 MHz -> 820 hex
