LIN Spec 2.1 (Par. 30)
1) Not subject to production test, specified by design
2) Minimum limit specified by design
3) Maximum limit specified by design
4) V_{BUS_CNT} = (V_{th_dom} + V_{th rec})/2;
5) V_HYS = V_BUSrec - V_BUSdom
6) Bus load concerning LIN Spec 2.1:
Load 1 = 1 nF / 1 kΩ = C_BUS / R_BUS
Load 2 = 6.8 nF / 660 Ω = C_BUS / R_BUS
Load 3 = 10 nF / 500 Ω = C_BUS / R_BUS
