The first time the device is set in Normal mode, the CAN is in Sleep wake-up enable (bit7 = 1, bit 6 =0). The next time the device is
set in Normal mode, the CAN state is controlled by bits 7 and 6.

Default state
CAN mod[1], CAN mod[0] - CAN interface mode control, wake-up enable / disable
CAN interface in Sleep mode, CAN wake-up disable.
CAN interface in receive only mode, CAN driver disable.
CAN interface is in Sleep mode, CAN wake-up enable. In device low power mode,
CAN wake-up is reported by device wake-up. In device normal mode, CAN wake-up reported by INT.
CAN interface in transmit and receive mode.

Single dominant pulse wake-up mechanism
CAN INT - Select the CAN failure detection reporting
Select INT generation when a bus failure is fully identified and decoded (i.e after 5 dominant pulses on TxCAN)
Select INT generation as soon as a bus failure is detected, event if not fully identified
