8.2.14 ATL PTD Skip Map register
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 normally be set on
the position indicated by NextPTDPointer.
The bit description of the register is given in
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 normally be set to a higher position than any other position indicated by
the NextPTDPointer from an active PTD.
Table 31
This register represents a direct map of the done status of the 32 PTDs. The bit
corresponding to a certain PTD will be set to logic 1 as soon as that PTD execution is
completed. Reading the Done Map register will clear all the bits that are set to logic 1, and
the next reading will reflect the updated status of new executed PTDs.
