Appendix B: Register Details
PTC
(PORTSCR_PTC)
19:16 rw 0x0 Port Test Control.
0000: Normal operation.
All others are test modes:
0001: J_STATE
0010: K_STATE
0011: SE0 (host) / NAK (device)
0100: Packet
0101: FORCE_ENABLE_HS
0110: FORCE_ENABLE_FS
0111: FORCE_ENABLE_LS
Others: reserved
PIC
(PORTSCR_PIC)
15:14 rw 0x0 Port Indicator Control outputs (EHCI) (Host
mode).
00: Port indicators are off.
01: Amber (PL output signal
EMIOUSBxPORTINDCTL0 is driven High).
10: Green (PL output signal
EMIOUSBxPORTINDCTL1 is driven High).
11: undefined.
Refer to the USB Specification Revision 2.0 for a
description on how these bits are to be used.
PO
(PORTSCR_PO)
13 ro 0x0 Port Owner hand off is not implemented.
Hardwired to 0.
PP
(PORTSCR_PP)
12 rw 0x0 Port Power enable (ECHI) (Host mode).
Controls the PL output signal
EMIOUSBxVBUSPWRSELECT.
0: disable, driven Low.
1: enable, driven High.
This bit represents the current setting of the
switch ('0'=off, '1'=on). When power is not
available on a port (i.e. [PP] equals to '0'), the port
is non-functional and will not report attaches,
detaches, etc.
When an over-current condition is detected on a
powered port and [PPC] is a one, the [PP] bit in
each affected port may be transitioned by the
controller driver from '1' to '0'(removing power
from the port).
LS
(PORTSCR_LS)
11:10 ro 0x0 Line State:
00: SE0
01: J-state
10: K-state
11: undefined.
