It is also not necessary to initially prime Endpoint 0 because the first packet received will always be a setup
packet. The contents of the first setup packet will require a response in accordance with USB device
framework command set.
21.8.2
From a chip or system reset, the USB controller enters the powered state. A transition from the powered
state to the attach state occurs when the run/stop bit (USBCMD[RS]) is set to a '1'. After receiving a reset
on the bus, the port will enter the defaultFS or defaultHS state in accordance with the protocol reset
described in Appendix C.2 of the USB Specification Rev. 2.0. The following state diagram depicts the state
of a USB 2.0 device.

6. Configure the ENDPOINTLISTADDR pointer.
7. Enable the microprocessor interrupt associated with the USB module and optionally change setting
8. Set USBCMD[RS] to run mode.

of USBCMD[ITC].
Recommended: enable all device interrupts including: USBINT, USBERRINT, Port Change
Detect, USB Reset Received, DCSuspend.
For a list of available interrupts refer to the USBINTR and the USBSTS register tables.
After the run bit is set, a device reset will occur. The DCD must monitor the reset event and set the
DEVICEADDR register, set the ENDPTCTRLx registers, and adjust the software state as
described in the Bus Reset section of the following Port State and Control section below.
Port State and Control
All device queue heads must be initialized for control endpoints before the
endpoint is enabled. Device queue heads for non-control endpoints must be
initialized before the endpoint can be used.
Endpoint 0 is designed as a control endpoint only and does not need to be
configured using ENDPTCTRL0 register.
