    Question:

    What is the state of RXD and BUS pins during a low-voltage reset?

     

    Answer:

    The  RXD and the BUS pins are in High-Z state in a low-voltage reset. Therefore, the output stage is disabled and communication to the CXPI BUS is not possible. After releasing the low-voltage reset, a HIGH is output to the BUS pin after a clock input of 33 periods. For details, refer to the "Low-voltage Reset" chapter in the datasheet from the following link.
