The OTG software stack is responsible for implementing the HNP state machines as
described in the On-The-Go Supplement to the USB 2.0 Specification.
The OTG controller hardware provides support for some of the state transitions in the
HNP state machines as described in the following subsections.
The USB state machines, the HNP switching, and the communications between the USB
controllers are described in more detail in the following documentation:
In this case, the default role of the OTG controller is peripheral (B-device), and it switches
roles from Peripheral to Host.
The On-The-Go Supplement defines the behavior of a dual-role B-device during HNP
using a state machine diagram. The OTG software stack is responsible for implementing
all of the states in the Dual-Role B-Device State Diagram.
The OTG controller hardware provides support for the state transitions between the states
b_peripheral, b_wait_acon, and b_host in the Dual-Role B-Device state diagram. Setting
B_HNP_TRACK in the OTGStCtrl register enables hardware support for the B-device
switching from peripheral to host. The hardware actions after setting this bit are shown in
