Will TJA1043 wake up from normal CAN traffic

If I understand the specs of the TJA1043 and of CAN the remote wake up pattern is simple (a dominant time of 0.5-3usec, followed by similar length recessive time, followed by another dominant time of similar length. It looks like any '101' pattern in a message at 500kbps will be recognized as WUP. In other words - almost any traffic will wake up the TJA1043. Is this right? Or am I missing something?

Thanks,

Freddy
