7.3.4.11 Protection for MCU I/Os
In many conditions, such as the negative ISO pulse, or the loss of battery with an inductive load, a negative potential on the device GND pin can damage the MCU I/O pins (more likely, the internal circuitry connected to the pins). Therefore, the serial resistors between MCU and HSS are required.
Also, for proper protection against loss of GND, TI recommends 5-kΩ resistance for the RPROT resistors.
