as the controller can automatically split for bulk transactions if the FIFO is larger than the maximum
packet size. The FIFO can also be configured as a double-buffered FIFO so that interrupts occur
at the end of each packet and allow filling the other half of the FIFO.
If operating as a device, the USB device controllers' soft connect should be enabled when the device
is ready to start communications. This indicates to the host controller that the device is ready to
start the enumeration process. If operating as a host controller, the device soft connect should be
disabled and power should be provided to VBUS via the USB0EPEN signal.
