ISO PTD Done Map register (address 0130h) bit description
8.2.7 ISO PTD Done Map register
8.2.8 ISO PTD Skip Map register
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.

shows the bit description of the register.
PORTSC1 - Port Status and Control 1 register (address 0064h) bit description
Port Test Control: When this ﬁeld is zero, the port is not operating in test
mode. A nonzero value indicates that it is operating in test mode indicated
by the value.
Port Indicator Control: Writing to this ﬁeld has no effect if the
P_INDICATOR bit in the HCSPARAMS register is logic 0.
For a description on how these bits are implemented, refer to
“Universal Serial Bus Speciﬁcation Rev.
Port Owner: This bit unconditionally goes to logic 0 when the conﬁgured
bit in the CONFIGFLAG register makes a logic 0 to logic 1 transition. This
bit unconditionally goes to logic 1 whenever the conﬁgured bit is logic 0.
Port Power: The function of this bit depends on the value of the PPC (Port
Power Control) ﬁeld in the HCSPARAMS register.
Line Status: This ﬁeld reﬂects the current logical levels of the DP (bit 11)
and DM (bit 10) signal lines.
Port Reset: Logic 1 means the port is in the reset state. Logic 0 means
the port is not in reset.
Suspend: Logic 1 means the port is in the suspend state. Logic 0 means
the port is not suspended.
Force Port Resume: Logic 1 means resume detected or driven on the
port. Logic 0 means no resume (K-state) detected or driven on the port.
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.
