    How to use CTS to wake up CYW20706 by host MCU

      Dear Forum,


      I've found in datasheet that CYW20706 supports CTS wake up when talking about HCI UART


      1. Low-power out-of-band BT_WAKE and HOST_WAKE signaling (datasheet section 1.1)

      2. The CYW20706 UART can perform XON/XOFF flow control and includes hardware support for the Serial Line Input Protocol (SLIP).
      It can also perform wake-on activity. For example, activity on the RX or CTS inputs can wake the chip from a sleep state
        (datasheet section 5.3)

      Would you please tell how to implement the BT_WAKE or HOST_WAKE via UART?



      Best Regards,

      Tim Yu
