    FM0 MFS UART FIFO Function Always Returns 0xFF

      Hello,

      I am using a FM0+ is a design and am trying to communicate with the FM0+ from another micro using a UART. The problem I am having is the FIFO accessor functions (Mfs_Uart_GetFifoCount() and the like) are always returning 0xFF. I don't understand this behavior as nothing should be in the Fifo and I have verified there is not activity on the serial receive line.

       

      Could you take a look at the attached project and let me know if I am doing something incorrectly? Like setting up the UART incorrectly, etc? It is strange behavior that I don't understand.

       

      Thanks in advance.
