Register Description
2.10.31 MC_CHANNEL_0_PAGETABLE_PARAMS1
MC_CHANNEL_1_PAGETABLE_PARAMS1
MC_CHANNEL_2_PAGETABLE_PARAMS1
These are the parameters used to control parameters for page closing policies..
2.10.32 MC_CHANNEL_0_PAGETABLE_PARAMS2
MC_CHANNEL_1_PAGETABLE_PARAMS2
MC_CHANNEL_2_PAGETABLE_PARAMS2
These are the parameters used to control parameters for page closing policies..
Device: 4, 5, 6
Function: 0
Offset: D8h
Access as a Dword

Description
15:8 RW 0 REQUESTCOUNTER.
This field is the 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.
This field is the 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.

Description
27 RW 0 ENABLEADAPTIVEPAGECLOSE.
1 = Enables Adaptive Page Closing.
26:18 RW 0 MINPAGECLOSELIMIT.
This field is the 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.
This field is the 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.
This field is the 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.
