8. In accordance to LIN physical layer specification 1.3.
9. In accordance to LIN physical layer specification 2.0.
10. Propagation delays are not relevant for LIN protocol transmission, only symmetry.
11. No production test, guaranteed by design and qualification.
12. See Figure 2 − Input/Output Timing.
13. See Figure 7 − Slope Time Calculation.
14. See Figure 3 − Receiver Debouncing.
15. This parameter is tested by applying a square wave to the bus. The minimum slew rate for the bus rising and falling edges is 50 V/ms.
16. See Figure 8 − Duty Cycle Measurement and Calculation.
