Notes:
1. Orin SPI3 is connected to an ultrasonic ASIC. An IO expander controlled by Orin I2C4 is used for scanning up to 12
ultrasonic sensors.
2. Fused ultrasonic power output from a high-side switch enabled via IO expander controlled by Orin I2C4.
3. Wake-up capable CAN port.
4. Minimum WUP_IN voltage is 2.5V.
5. This pin, combined with H1 pin-31, supports up to 40mA of 3.3V current when Aurix is powered.
