+1500
Each interruption is 150 ns.
The transition time from Data_0 to Data_1 and from Data_1 to Data_0 is about 20 ns.
The TJA1080A wake-up flag will be set with the following pattern:
FFh, FFh, FFh, FFh, FFh, 00h, 00h, 00h, 00h, 00h,
FFh, FFh, FFh, FFh, FFh, 00h, 00h, 00h, 00h, 00h,

If the voltage on pin WAKE is lower than V
edge on pin WAKE) a local wake-up event on pin WAKE is detected. At the same time, the
biasing of this pin is switched to pull-down.
If the voltage on pin WAKE is higher than V
biasing of this pin is switched to pull-up, and no local wake-up will be detected.
