At the moment, the CAN0 transciever is always kept enabled (even in low-power mode) to support CAN-based ignition.
Providing that these cars trigger the bus wakeup request, we can also put this transciever in standby mode and listen for an interrupt on the corresponding RXD pin.
This should save about 25mW in low-power mode.
