gotgint

The application reads this register whenever there is an OTG interrupt and clears the bits in this register to clear the OTG interrupt.

Important: To prevent indeterminate system behavior, reserved areas of memory must not be accessed by software or hardware. Any area of the memory map that is not explicitly defined as a register space or accessible memory is considered reserved.

Access

Reset

dbncedone

Mode: Host only. The core sets this bit when the debounce is completed after the device connect. The application can start driving USB reset after seeing this interrupt. This bit is only valid when the HNP Capable or SRP Capable bit is SET in the Core USB Configuration register (GUSBCFG.HNPCap or GUSBCFG.SRPCap, respectively). This bit can be set only by the core and the application should write 1 to clear it.

Value	Description
0x0	No Change
0x1	Debounce completed

RO

0x0

adevtoutchg

Mode:Host and Device. The core sets this bit to indicate that the A-device has timed out WHILE waiting FOR the B-device to connect. This bit can be set only by the core and the application should write 1 to clear it.

Value	Description
0x0	No Change
0x1	A-Device Timeout

RO

0x0

hstnegdet

Mode:Host and Device. The core sets this bit when it detects a host negotiation request on the USB. This bit can be set only by the core and the application should write 1 to clear it.

Value	Description
0x0	No Change
0x1	Host Negotiation Detected

RO

0x0

hstnegsucstschng

Mode: Host and Device. The core sets this bit on the success or failure of a USB host negotiation request. The application must read the Host Negotiation Success bit of the OTG Control and Status register (GOTGCTL.HstNegScs) to check for success or failure. This bit can be set only by the core and the application should write 1 to clear it.

Value	Description
0x0	No Change
0x1	Host Negotiation Status Change

RO

0x0

sesreqsucstschng

Mode: Host and Device. The core sets this bit on the success or failure of a session request. The application must read the Session Request Success bit in the OTG Control and Status register (GOTGCTL.SesReqScs) to check for success or failure. This bit can be set only by the core and the application should write 1 to clear it.

Value	Description
0x0	No change
0x1	Session Request Status

RO

0x0

sesenddet

Mode:Host and Device.This bit can be set only by the core and the application should write 1 to clear it.

Value	Description
0x0	Non Active State
0x1	Set when utmisrp_bvalid signal is deasserted

RO

0x0
