4-2-8. Simple Debugging
The JOB60851 board allows simple debugging over the serial link to a terminal emulator with
printf(), scanf(), and other C standard I/O library functions. Also available for use in debugging is
LED2, which is connected to Port 7 and thus under program control. For further details, see Sections
4.4 "Port 7 LED2 Control" and 4.5 "Standard I/O over Serial Link."
4-2-9. Evaluating USB Equipment
The USB Implementers Forum has published USB interface compliance guidelines. The following
URL provides access to guidelines and peripheral check lists for power consumption, UBS device
framework (using Usbcheck.exe described above), and equipment configurations for testing
interconnectivity.

Every three or four months, the USB Implementers Forum conducts a compliance workshop for
testing interconnectivity. Passing these tests earns the devices the right to use the USB logo.
