I set the STB pin to HIGH to make the CAN  transceiver enter to STANDBY MODE ,but i can not wake-up the CAN  transceiver by sending a CAN messege .As followed shows requirement how to wake-up CAN requirement:

 I do make sure the CAN bus dominant and bus recessive states is longer than  tfltr(wake)bus ,but the RXD pin is still HIGH and would not be LOW.

Anyone can help me to slove this problem?
