Session Request: n 1'b0: No session request n 1'b1: Session request The 

application sets this bit to initiate a session request on the USB. Writing 1'b1 to this field 

will trigger the core to send SRP (data line pulsing) on PHY interface. In the absence of 

OEVT.OTGBDevSessVldDetEvnt after a session request, the application must wait for 

atleast TB_SRP_FAIL time (6 secs) before initiating another session request. This field 

returns 1'b0 when read.

TermSel DLine Pulsing Selection: This bit selects utmi_termselect to 

drive data line pulse during SRP. n 1'b0: Data line pulsing using utmi_txvalid (default). n 

1'b1: Data line pulsing using utmi_termsel.

Device Set RSP/HNP Enable: n 1'b0: RSP/HNP is not enabled in the 

application n 1'b1: RSP/HNP is enabled in the application The application sets this bit in 

the following scenario: n In HS/FS mode, when it successfully receives a 

SetFeature.SetHNPEnable command from the connected USB host. n In SS mode, when 

it has sent a b3_ntf_hst_rel to the A-device, or the A-device has sent an 

a3_ntf_host_req. Note: The terminology RSP is used when the core is operating in SS 

mode, and HNP is used when the core is operating in non-SS mode.

Host Set RSP/HNP Enable: n 1'b0: Host Set RSP/HNP is not enabled n 

1'b1: Host Set RSP/HNP is enabled The application sets this bit in the following scenario: 

n In HS/FS mode, when it has successfully enabled HNP (using the 

SetFeature.SetHNPEnable command) from the connected device. n In SS mode, when it 

has successfully enabled b3_rsp_enable feature in RSP-capable Device using SetFeature 

command while operating as an A-Host, or when it has received a b3_ntf_hst_rel 

through SetFeature command while operating as A-peripheral. Note: The terminology 

RSP is used when the core is operating in SS mode, and HNP is used when the core is 

operating in non-SS mode.
