20.Receive delay time is measured from the rising / falling edge crossing of the nominal Vih value on CANH to the falling (Vcmos_il_max) / rising
(Vcmos_ih_min) edge of RxD. This parameter is tested by applying a square wave signal to CANH. The minimum slew rate for the bus rising
and falling edges is 50 V/ms. The low level on bus is always 0 V. For normal mode and high−speed mode testing the high level on bus is 4 V.
For HVWU mode testing the high level on bus is V

− 2 V. Relaxation of this non−critical parameter from 0.15 ms to 0.10 ms may be addressed
in future revisions of GMW3089.
