USB on-the-go full-speed (OTG_FS)
734/995
Bit 3 SOF: Start of frame
Bit 2 OTGINT: OTG interrupt
Bit 1 MMIS: Mode mismatch interrupt
Bit 0 CMOD: Current mode of operation
In Host mode, the core sets this bit to indicate that an SOF (FS), or Keep-Alive (LS) is
transmitted on the USB. The application must write a 1 to this bit to clear the interrupt.
In Device mode, in the core sets this bit to indicate that an SOF token has been received on
the USB. The application can read the Device Status register to get the current frame number.
This interrupt is seen only when the core is operating in FS.
Note: Accessible in both Host and Device modes.
The core sets this bit to indicate an OTG protocol event. The application must read the OTG
Interrupt Status (OTG_FS_GOTGINT) register to determine the exact event that caused this
interrupt. The application must clear the appropriate status bit in the OTG_FS_GOTGINT
register to clear this bit.
Note: Accessible in both Host and Device modes.
The core sets this bit when the application is trying to access:
The register access is completed on the AHB with an OKAY response, but is ignored by the
core internally and does not affect the operation of the core.
Note: Accessible in both Host and Device modes.
Indicates the current mode.
Note: Accessible in both Host and Device modes.
