Bit 10 HSHNPEN: host set HNP enable
The application sets this bit when it has successfully enabled HNP (using the
SetFeature.SetHNPEnable command) on the connected device.
0: Host Set HNP is not enabled
1: Host Set HNP is enabled
Note: Only accessible in host mode.
Bit 9 HNPRQ: HNP request
The application sets this bit to initiate an HNP request to the connected USB host. The
application can clear this bit by writing a 0 when the host negotiation success status change
bit in the OTG_GOTGINT register (HNSSCHG bit in OTG_GOTGINT) is set. The core clears
this bit when the HNSSCHG bit is cleared.
0: No HNP request
1: HNP request
Note: Only accessible in device mode.
Bit 8 HNGSCS: Host negotiation success
The core sets this bit when host negotiation is successful. The core clears this bit when the
HNP request (HNPRQ) bit in this register is set.
0: Host negotiation failure
1: Host negotiation success
Note: Only accessible in device mode.
Bit 7 BVALOVAL: B-peripheral session valid override value.
This bit is used to set override value for Bvalid signal when BVALOEN bit is set.
0: Bvalid value is '0' when BVALOEN = 1
1: Bvalid value is '1' when BVALOEN = 1
Note: Only accessible in device mode.
Bit 6 BVALOEN: B-peripheral session valid override enable.
This bit is used to enable/disable the software to override the Bvalid signal using the
BVALOVAL bit.
0:Override is disabled and Bvalid signal from the respective PHY selected is used internally
by the core
1:Internally Bvalid received from the PHY is overridden with BVALOVAL bit value
Note: Only accessible in device mode.
Bit 5 AVALOVAL: A-peripheral session valid override value.
This bit is used to set override value for Avalid signal when AVALOEN bit is set.
0: Avalid value is '0' when AVALOEN = 1
1: Avalid value is '1' when AVALOEN = 1
Note: Only accessible in host mode.
Bit 4 AVALOEN: A-peripheral session valid override enable.
This bit is used to enable/disable the software to override the Avalid signal using the
AVALOVAL bit.
0:Override is disabled and Avalid signal from the respective PHY selected is used internally
by the core
1:Internally Avalid received from the PHY is overridden with AVALOVAL bit value
Note: Only accessible in host mode.
