    Dummy byte is received when wakeup source is not UART

      Hello, I am struggling on the PSOC4 deepsleep. 0xFF is received when wakeup source is not UART. I find the UART low power note in the UART component datasheet.

       

      0xFF is gone after applying this workaround. But I have to add more preamble bytes before the real data. It is very inconvenient.

       

      Is there a solution or workaround to  resolve this issue better?
