CODE EXAMPLE 4-15 identifies the parallel port output message.
4.7.8 Serial Port A
The serial port A diagnostic invokes the uart_loopback test. The
uart_loopback test transmits and receives 128 characters and checks the
transaction validity. The following baud rates are tested in asynchronous mode:
460800, 307200, 230400, 153600, 76800, 57600, 38400, 19200, 9600, 4800, 2400, and 800.
CODE EXAMPLE 4-16 identifies the serial port A output message.
