TCAN1146-Q1: TCAN1146 Sleep mode and Selective wake

Part Number: TCAN1146-Q1

Hi team:

    Initialize the TCAN1146 MODE_CNTRL register to 0x01 that means enter Sleep mode and disable selective wake, but if specific data appears on the CAN bus at this time, TCAN1146 will enter standby mode(MODE_CNTRL is 0x04) and generate a CANINT interrupt from the INT_1 Register.

    It should be noted that specific data is the WUF used in previous test the selective wake, other CAN data doesn't seem to be like this.

   Why does DISABLE selective wake still generate CANINT interrupt?

 

Thanks for your suggestion.

Best regards,

Fedora
