(4) Device State Transition Interrupt
Figure 25.6 shows a diagram of this module device state transitions. This module controls device
states and generates device state transition interrupts. However, recovery from the suspended state
(resume signal detection) is detected by means of the resume interrupt. The device state transition
interrupts can be enabled or disabled individually using INTENB0. The device state that made a
transition can be confirmed using the DVSQ bit in INTSTS0.
To make a transition to the default state, the device state transition interrupt is generated after the
reset handshake protocol has been completed.
Device state can be controlled only when the function controller function is selected. Also, the
device state transition interrupts can be generated only when the function controller function is
selected.
