Write Behavior: oneToClear A-device B-Host End Event: Set 

in A-device Mode Only. The event is generated when B-device hascompleted its host 

role. Note: This bit is applicable for OTG 2.0 and OTG 3.0 modes of operation.

RO

Write Behavior: oneToClear A-device host event: Set in A-device 

Mode Only. This event is generated when A-device enters host role. In HS/FS mode, it 

occurs after the initial connect to a B-device as A-host as well as when there is a role 

change from A-peripheral to A-host. Note: This bit is applicable only for OTG 2.0 mode 

of operation.

Write Behavior: oneToClear A-Dev HNP Change Event: Set in 

A-device Mode Only. The event is generated when there is an HNP attempt. Note: This 

bit is applicable only for OTG 2.0 mode of operation.

Write Behavior: oneToClear SRP Detect Event: Set in A-device 

Mode Only. This event is asserted when a session request from the B-device is detected 

via SRP. Note: This bit is applicable for OTG 2.0 and OTG 3.0 modes of operation.

Write Behavior: oneToClear Session End Detected Event: 

Set in A-device Mode Only. This event is asserted when the utmisrp_avalid signal goes 

low indicating the end of a session. Note: This bit is applicable for OTG 2.0 and OTG 3.0 

modes of operation

in B-device Mode Only. This event is generated when B-device has completed its host 

role. Note: This bit is applicable for OTG 2.0 and OTG 3.0 modes of operation.

Write Behavior: oneToClear B-Dev HNP Change Event: Set in 

B-Device Mode only. This event is generated when there is a Success or Failure of an 

HNP attempt. Note: This bit is applicable for OTG 2.0 and OTG 3.0 modes of operation.

Write Behavior: oneToClear Session Valid Detected Event: 

Set in B-device Mode Only. This event is asserted when there is a valid Vbus from A-

device and B-device succeeds in starting a session. Note: This bit is applicable for OTG 

2.0 and OTG 3.0 modes of operation.

(indicating the end of a session), or goes high. Note: This bit is applicable for OTG 2.0 

and OTG 3.0 modes of operation.

Indicates the Device mode transceiver status. Indicates the Device mode 

transceiver status. The core updates this bit when OEVTEN.OTGBDevVBUSChngEvnt is 

set. 1b0: B-session is not valid 1b1: B-session is valid Note: This bit is applicable for 

OTG 2.0 and OTG 3.0 modes of operation.

Host Negotiation Status: The core updates this bit when any of the 

following bits is set: n OEVTEN.OTGADevHNPChngEvnt n 

OEVTEN.OTGBDevHNPChngEvnt This bit indicates Host Negotiation Success or Failure. n 

1'b0: Host negotiation failure. In A-device, for HS/FS, this indicates an imminent end of 

session indication from the core. In B-device, for HS/LS, it indicates that the timer used 

to wait for an A-device to signal a connection (b_ase0_brst_tmout in OTG 2.0) timed out 

resulting in B-device staying as B-peripheral. n 1'b1: Host negotiation success. This 

indicates that the host negotiation was successful. Note: This bit is a pplicable only for 

OTG 2.0 mode of operation.
