JAJSOK5Q March 2011 – March 2024 TUSB7320 , TUSB7340
PRODUCTION DATA
The TUSB73X0 implements a Port Status and Control Register for each port that is implemented. The number of Port Status and Control Registers is the same as the value in the MAX_PORTS field in the Host Controller Structural Parameters 1 Register (see Host Controller Structural Parameters 1).
Operational Base register offset: 400h + (10h × (n-1))), where n = Port Number
Register type: Read-Only, Read/Write, Read/Clear
Default value: X000 02A0h

BIT | FIELD NAME | ACCESS | DESCRIPTION |
---|---|---|---|
31 | WPR(1) | rc or r | Warm Port Reset. This field is only valid for USB 3.0 protocol ports. For USB 2.0 protocol ports, this bit is reserved. |
30 | DR | r | Device Removable. The value of this bit depends on the value programmed into the USBx_PORTy_NON_REM bit in the USB Control Register that corresponds to the port number and port type associated with this register. |
29:28 | RSVD | r | Reserved. Returns zeros when read. |
27 | WOE(1) | rw | Wake on Overcurrent Enable. |
26 | WDE(1) | rw | Wake on Disconnect Enable. |
25 | WCE(1) | rw | Wake on Connect Enable. |
24 | RSVD | r | Reserved. Return zero when read. |
23 | CEC(1) | rc or r | Port Config Error Change. This field is only valid for USB 3.0 protocol ports. For USB 2.0 protocol ports, this bit is reserved. |
22 | PLC(1) | rc | Port Link State Change. |
21 | PRC(1) | rc | Port Reset Change. |
20 | OCC(1) | rc | Overcurrent Change. |
19 | WRC(1) | rc or r | Warm Port Reset Change. This field is only valid for USB 3.0 protocol ports. For USB 2.0 protocol ports, this bit is reserved. |
18 | PEC(1) | rc | Port Enabled/Disabled Change. |
17 | CSC(1) | rc | Connect Status Change. |
16 | LWS | w | Port Link State Write Strobe. This bit returns a zero when read. |
15:14 | PIC(1) | rw | Port Indicator Control. Because the TUSB73X0 does not support port indicators, this field has no effect. |
13:10 | PORT_SPEED(1) | r | Port Speed |
9 | PP(1) | rw | Port Power. |
8:5 | PLS(1) | rw | Port Link State |
4 | PR(1) | rs | Port Reset. |
3 | OCA | r | Overcurrent Active. |
2 | RSVD | r | Reserved. Returns zero when read. |
1 | PED(1) | rc | Port Enabled/Disabled. |
0 | CCS(1) | r | Current Connect Status. |
