+ *
+ * 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.
