+Configuration Table Use
+=======================
+
+sDeviceName
+
+ The name of this device.
+
+deviceType
+
+ This field must be SERIAL_MG5UART.
+
+pDeviceFns
+
+ The device interface control table. This may be:
+ + mg5uart_fns for interrupt driven IO
+ + mg5uart_fns_polled for polled IO
+
+deviceProbe
+
+ This is the address of the routine which probes to see if the device
+ is present.
+
+pDeviceFlow
+
+ This field is ignored as hardware flow control is not currently supported.
+
+ulMargin
+
+ This is currently unused.
+
+ulHysteresis
+
+ This is currently unused.
+
+pDeviceParams
+
+ This is set to the default settings.
+
+ulCtrlPort1
+
+ This field is the address of the command register shared by both ports.
+
+ulCtrlPort2
+
+ This field is the address of the port being used.
+
+ulDataPort
+
+ This field is set to MG5UART_PORTA or MG5UART_PORTB.
+
+getRegister
+setRegister
+
+ These do NOT follow standard conventions and are ignored.
+ The register address routines are hard-coded as this is
+ an on-CPU part and assumed to provide a 32-bit wide interface.
+
+getData
+
+ This is address of the RX buffer register.
+
+setData
+
+ This is address of the TX buffer register.
+
+ulClock
+
+ baudRate Clock
+
+ulIntVector
+
+ This is the interrupt vector number associated with this chip.
+
+Example:
+
+#if (CONSOLE_USE_INTERRUPTS)
+#define MG5UART_FUNCTIONS &mg5uart_fns
+#else
+#define MG5UART_FUNCTIONS &mg5uart_fns_polled
+#endif
