The bit description of the register is given in
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.
Table 26
When a bit in the PTD Skip Map is set to logic 1, the corresponding PTD will be skipped,
independent of the V bit setting. 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.
Table 27
Once the LastPTD bit corresponding to a PTD is set, this will be the last PTD processed
(checking V = logic 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
Description
Port Enabled/Disabled: Logic 1 means enable. Logic 0 means disable.
Connect Status Change: Logic 1 means change in ECCS. Logic 0 means no change.
Current Connect Status: Logic 1 indicates a device is present on the port. Logic 0 indicates
no device is present.
