Sof [3]
R_SS_
WC
Start of (micro) Frame
In Host mode, the core sets this bit to indicate that
an SOF (FS), micro-SOF (HS), 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
(micro)frame number. This interrupt is seen only
when the core is operating at either HS or FS.

RO
OTG Interrupt
The core sets this bit to indicate an OTG protocol
event. The application must read the OTG Interrupt
Status (GOTGINT) register to determine the exact
event that caused this interrupt. The application must
clear the appropriate status bit in the GOTGINT
register to clear this bit.

Mode Mismatch Interrupt
The core sets this bit when the application is trying to
access:
·
A Host mode register, when the core is operating in
Device mode
·
A Device mode register, when the core is operating
in Host mode

CORE INTERRUPT MASK REGISTER (GINTMSK)
This register works with the Core Interrupt register to interrupt the application. When an interrupt bit is masked,
the interrupt associated with that bit will not be generated. However, the Core Interrupt (GINTSTS) register bit
corresponding to that interrupt will still be set.
