[1] This parameter is tested by applying a square wave signal to the LIN. The minimum slew rate for the LIN rising and falling
edges is 50V/us
[2] See figure 4 - receiver debounce and propagation delay
[3] See figure 5 and 6 – duty cycle measurement & calculation,
[4] Standard loads for duty cycle measurements are 1KΩ/1nF , 660Ω/6.8nF, 500Ω/10nF,internal termination disabled
