A detailed example of a program that uses Autovectoring is presented in Section 6.14,
"Interrupt Bulk Transfer Example." The coding steps are summarized here. To employ
EZ-USB Autovectoring:
EZ-USB TRM v1.9
9.11
1. Insert a jump instruction at 0x43 to a table of jump instructions to the various USB
interrupt service routines.
