Test Points
When using JTAG ICE MK II for debugging, and as AT90USB1287 parts are factory configured
with the higher security level set, a chip erase operation will be performed on the part before
debugging. Thus the on-chip flash bootloader will be erased. It can be restored after the debug
session using the bootloader hex file available from ATMEL website.
There are 4 test points implemented, these test points are referenced in the full schematics section.
