to the USB_I2C_INT bit.
For more details on the interrupts created by device controller, see the USB device
chapter. For interrupts created by the host controllers, see the OHCI specification.
The EN_USB_INTS bit in the USBIntSt register enables the routing of any of the USB
related interrupts to the NVIC controller (see
Remark: During the HNP switching between host and device with the OTG stack active,
an action may raise several levels of interrupts. It is advised to let the OTG stack initiate
any actions based on interrupts and ignore device and host level interrupts. This means
that during HNP switching, the OTG stack provides the communication to the host and
device controllers.
This section describes the hardware support for the Host Negotiation Protocol (HNP)
provided by the OTG controller.
When two dual-role OTG devices are connected to each other, the plug inserted into the
mini-AB receptacle determines the default role of each device. The device with the mini-A
plug inserted becomes the default Host (A-device), and the device with the mini-B plug
inserted becomes the default Peripheral (B-device).
Once connected, the default Host (A-device) and the default Peripheral (B-device) can
switch Host and Peripheral roles using HNP.
The context of the OTG controller operation is shown in
Device, or OTG) communicates with its software stack through a set of status and control
registers and interrupts. In addition, the OTG software stack communicates with the
external OTG transceiver through the I
signal.
