REQUESTCOUNTER
Upper 8 MSBs of a 12-bit counter. This counter determines the window over
which the page close policy is evaluated.
7:0 RW 0
ADAPTIVETIMEOUTCOUNTER
Upper 8 MSBs of a 12-bit counter. This counter adapts the interval between
assertions of the page close flag. For a less aggressive page close, the length
of the count interval is increased and vice versa for a more aggressive page
close policy.

ENABLEADAPTIVEPAGECLOSE
When set, enables Adaptive Page Closing.
26:18 RW 0
MINPAGECLOSELIMIT
Upper 9 MSBs of a 13-bit threshold limit. When the mistake counter falls
below this threshold, a less aggressive page close interval (larger) is
selected.
17:9 RW 0
MAXPAGECLOSELIMIT
Upper 9 bits of a 13-bit threshold limit. When the mistake counter exceeds
this threshold, a more aggressive page close interval (smaller) is selected.
8:0 RW 0
MISTAKECOUNTER
Upper 9 MSBs of a 12-bit counter. This counter adapts the interval
between assertions of the page close flag. For a less aggressive page
close, the length of the count interval is increased and vice versa for a
more aggressive page close policy.
