Bits 15:12 Reserved
Bit 19 BSVLD: B-session valid
Bit 18 ASVLD: A-session valid
Bit 17 DBCT: Long/short debounce time
Bit 16 CIDSTS: Connector ID status
Bit 11 DHNPEN: Device HNP enabled
Bit 10 HSHNPEN: Host set HNP enable
Bit 9 HNPRQ: HNP request
Indicates the Device mode transceiver status.
In OTG mode, you can use this bit to determine if the device is connected or disconnected.
Note: Only accessible in Device mode.
Indicates the Host mode transceiver status.
Note: Only accessible in Host mode.
Indicates the debounce time of a detected connection.
Note: Only accessible in Host mode.
Indicates the connector ID status on a connect event.
Note: Accessible in both Device and Host modes.
The application sets this bit when it successfully receives a SetFeature.SetHNPEnable
command from the connected USB host.
Note: Only accessible in Device mode.
The application sets this bit when it has successfully enabled HNP (using the
SetFeature.SetHNPEnable command) on the connected device.
Note: Only accessible in Host mode.
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 interrupt register (HNSSCHG bit in OTG_FS_GOTGINT) is set. The core clears this
bit when the HNSSCHG bit is cleared.
Note: Only accessible in Device mode.
0: B-session is not valid.
1: B-session is valid.
0: A-session is not valid
1: A-session is valid
0: Long debounce time, used for physical connections (100 ms + 2.5 µs)
1: Short debounce time, used for soft connections (2.5 µs)
0: The OTG_FS controller is in A-Device mode
1: The OTG_FS controller is in B-Device mode
0: HNP is not enabled in the application
1: HNP is enabled in the application
0: Host Set HNP is not enabled
1: Host Set HNP is enabled
0: No HNP request
1: HNP request
