5 UCAN is the protocol used by the microcontroller-based USB-CAN
6 adapter that is integrated on System-on-Modules from Theobroma Systems
9 The UCAN protocol has been designed to be hardware-independent.

315 - The device does not recover from bus of automatically.
316 - Bus OFF is indicated by an error frame (see ``uapi/linux/can/error.h``)
317 - Bus OFF recovery is started by ``UCAN_COMMAND_RESTART``
318 - Once Bus OFF recover is completed the device sends an error frame
319 indicating that it is on ERROR-ACTIVE state.
320 - During Bus OFF no frames are sent by the device.
321 - During Bus OFF transmission requests from the host are completed
