Description
Port Test Control: Default = 0000b. When this field is logic 0, the port is not
operating in test mode. A nonzero value indicates that it is operating in test
mode and test mode is indicated by the value. The encoding of the test mode
bits are:
0000b — Test mode disabled
0001b — Test J_STATE
0010b — Test K_STATE
0011b — Test SE0_NAK
0100b — Test packet
0101b — Test FORCE_ENABLE
0110b to 1111b — reserved.
Port Indicator Control: Default = 0. Writing to this field has no effect if
P_INDICATOR (bit 16) in the HCSPARAMS register is logic 0. If
P_INDICATOR is logic 1, then the bit encoding is:
00b — Port indicators are off
01b — Amber
10b — Green
11b — Undefined.
For a description on how these bits are implemented, refer to Universal
Serial Bus Specification Rev. 2.0 .
Port Owner: Default = 1. This bit unconditionally goes to logic 0 when CF
(bit 0) in the CONFIGFLAG register makes logic 0 to logic 1 transition. This
bit unconditionally goes to logic 1 when the CF bit is logic 0. The system
software uses this field to release ownership of the port to a selected Host
Controller, if the attached device is not a high-speed device. Software writes
logic 1 to this bit, if the attached device is not a high-speed device. Logic 1 in
this bit means that a companion Host Controller owns and controls the port.
Port Power: The function of this bit depends on the value of PPC (bit 4) in
the HCSPARAMS register.
If PPC = 0 and PP = 1 — The Host Controller does not have port power
control switches. Always powered.
If PPC = 1 and PP = 1 or 0 — The Host Controller has port power control
switches. This bit represents the current setting of the switch: logic 0 = off,
logic 1 = on. When PP is logic 0, the port is nonfunctional and will not report
any status.
When an overcurrent condition is detected on a powered port and PPC is
logic 1, the PP bit in each affected port may be changed by the Host
Controller from logic 1 to logic 0, removing power from the port.
