CURMOD=Val_0x0

Description

Global Status Register

Fields

CURMOD

Indicates the current mode of operation.

0 (Val_0x0): Device mode

1 (Val_0x1): Host mode

BUSERRADDRVLD

Bus error address valid. Indicates that the Global SoC Bus Error Address register (GBUSERRADDRLO or GBUSERRADDRHI) is valid and reports the first bus address that encounters a bus error. Write 0x1 to clear.

CSRTIMEOUT

CSR timeout. When this bit is set to 0x1, it indicates that the software performed a write or read to a controller register that could not be completed within predefined bus clock cycles (default: 0x1FFFF). Write 0x1 to clear.

DEVICE_IP

Device interrupt pending. This field indicates that there is a pending interrupt pertaining to peripheral (device) operation in the Device event queue.

HOST_IP

Host interrupt pending. This field indicates that there is a pending interrupt pertaining to xHC in the Host event queue.

ADP_IP

This bit is not used.

BC_IP

This bit is not used.

OTG_IP

This bit is not used.

SSIC_IP

This bit is not used.

CBELT

Current BELT value. In Host mode, this bit field indicates the minimum value of all received device BELT values and the BELT value that is set by the Set Latency Tolerance Value command.
