HNPCap: 
RSP/HNP Capability: 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. The 
application uses this bit to control the DWC_usb3 core's RSP/HNP capabilities. n 1'b0: 
RSP/HNP capability is not enabled. n 1'b1: RSP/HNP capability is enabled. Note: This bit 
is writable only if RSP/HNP mode is specified for Mode of Operation in coreConsultant, 
that is when DWC_USB3_EN_OTG != 0 and DWC_USB3_MODE = DRD. If RSP/HNP 
mode is not specified, this bit is Read Only, and is set to 1'b0.

SRPCap: 
SRP Capability: The application uses this bit to control the DWC_usb3 core's 
SRP capabilities. n 1'b0: SRP capability is not enabled. n 1'b1: SRP capability is enabled. 
If this bit is not set for B-device, it cannot request the connected A-device (host) to 
activate Vbus and start a session. If this bit is not set for A-device, it cannot detect the 
SRP from B-device (device) to activate Vbus and start a session. Note: This bit is 
writable only if OTG is enabled in coreConsultant (DWC_USB3_EN_OTG !=0). If OTG is 
not enabled, then this bit is Read Only and is set to 1'b0.

PeriMode: 
Peripheral Mode: Application uses this bit to program the core to work as a 
peripheral or as a host. n 1'b0: The OTG device acts as a host n 1'b1: The OTG device 
acts as a peripheral

PrtPwrCtl: 
Port Power Control: Application sets this bit to initiate Vbus drive when it is 
an A-device. The application should clearthis bit only if it wants to switch off the Vbus to 
B-device. The core clears this bit in the following conditions: n Transition from any state 
to A-IDLE state defined in OTG2.0 state machine. n When AIDL_BDIS_TOUT occurs in 
A_SUSPEND n When A_WAIT_BCON_TOUT occurs in A_WAIT_BCON n Transition to any 
B- state defined in OTG2.0 state machine

HNPReq: 
HNP Request: n 1'b0: No HNP request n 1'b1: HNP request The application 
sets this bit to initiate a HNP request to the connected USB host. The application clears 
this bit by writing a 1'b0 when either of the following is detected: n 
OEVT.OTGBDevBHostEndEvnt n OEVT.OTGBDevVBusChngEvnt
