Table 31:
When a bit in the PTD Skip Map is set to logic 1 that PTD will be skipped although its V bit
may be set. The information in that PTD is not processed. For example, NextPTDPointer
will not affect the order of processing of PTDs. The Skip bit should not be normally set on
the position indicated by NextPTDPointer.
The bit description of the ATL PTD Last PTD register is given in
Table 32:
Once the LastPTD bit corresponding to a PTD is set, this will be the last PTD processed
(checking V = 1) in that PTD category. Subsequently, the process will restart with the first
PTD (of that group). This is useful to reduce the time in which all the PTDs (the respective
memory space) would be checked, especially if only a few PTDs are defined. The
LastPTD bit must be normally set to a higher position than any other position indicated by
the NextPTDPointer from an active PTD.
