/* pDebuggerParameters string passed into __mriInit contains a space separated list of configuration parameters to be\r
   used to initialize the debug monitor.  The supported options include:\r
   \r
   One of these options to indicate which UART to be used for the debugger connection:\r
        MRI_UART_MBED_USB\r
        MRI_UART_MBED_P9_P10\r
        MRI_UART_MBED_P13_P14\r
        MRI_UART_MBED_P28_P27\r
        MRI_UART_0\r
        MRI_UART_1\r
        MRI_UART_2\r
        MRI_UART_3\r
        \r
    By default the debug monitor expects to take full control of the UART to configure baud rate, etc.  However \r
    including the following option will tell the monitor to assume that the user's firmware will configure and use the\r
    serial port until the first exception occurs:\r
        MRI_UART_SHARE\r
        \r
    When not sharing the UART, MRI will typically try to use the auto-baud functionality of the device so that the user\r
    can select the desired baud rate when they start GDB.  However it is possible to override this in the init string.\r
    For example the following option would set the baud rate to 230400 (note that spaces aren't allowed before or after\r
    the '=' character):\r
        MRI_UART_BAUD=230400\r
    NOTE: LPC176x version of MRI supports a maximum baud rate of 3Mbaud and the core clock can't run faster than\r
          128MHz or calculating baud rate divisors will fail.\r
