1) PLL jitter included.
2) Refers to delays caused by the asymmetries of the output drivers of the digital logic and the GPIO pad drivers.
Quartz tolerance and PLL jitter are not included.
3) TxD output drivers have an asymmetry of rising and falling edges of |t_F - t_R| ≤ 1 ns.
4) Valid for output slopes of the Bus Driver of dRxSlope ≤ 5 ns at C_L = 15 pF, 20% × V_DDP to 80% × V_DDP,
according to the FlexRay Electrical Physical Layer Specification V2.1 B.
