Hsinyu,

CAN WUP cannot be disabled on the TCAN4550-Q1. Please let us know if you have any other questions.

Hi Eric,

So, it is not possible to disable the function that exits sleep mode upon receiving CAN Rx, correct?

Hsinyu,

That is correct, this is inherent to the device and no configuration will disable it.
