Bus-off State Hold Until User Request — If BORM is set in MSCAN Control Register 1
indicates whether the module has entered the bus-off state. Clearing this bit requests the recovery from bus-off.
Refer to
0 Module is not bus-off or recovery has been requested by user in bus-off state
1 Module is bus-off and holds this state until user request
Writing to this register when in special system operating modes can alter the
