/** \file usbjt.h
*
* To use usbjt, you must tell the linker where to put the IN2JT.
* It must lie on a page boundary or your interrupts won't work right.
*
* example:
* -Wl"-b INT2JT = 0x1A00"
*
* Make sure that INT2JT doesn't overlap your other code!
*
* Unlike the standard fx2 interrupts (\ref fx2ints.h), the autovectored
* interrupts are defined in assemply and have pre-written function names.
* Be sure to override the functions defined in this header or your
* interrupt handler will not be called.
