4.4.3 Programming Interface 
A JTAG interface is provided for the AT90USB1287 microcontroller. The interface is 
available through a 50-mil spaced 10-pin dual row header. The RZRAVEN does not 
come with the header mounted. So it is up to the user populating it. Wires could also 
be soldered in instead of the dual row headers. A total of 5 50-mil pin headers and 
one 50-mil to 100-mil converter are supplied with the RZRAVEN kit.
