1443E–USB–4/04
The most typical and general program setup for the Reset and Interrupt Vector Addresses are:
USB related interrupt events are routed to reset vectors 13 and 2 through a separate set of
interrupt, interrupt enable and interrupt mask registers that are mapped to the data SRAM
space. These interrupts must be enabled though their control register bits. In the event an
interrupt is generated, the source of the interrupt is identified by reading the interrupt registers.
The USB frame and transaction related interrupt events, such as Start of Frame interrupt, are
grouped in one set of registers: USB Interrupt Flag Register and USB Interrupt Enable Regis-
ter. The USB Bus reset and suspend/resume are grouped in another set of registers:
Suspend/Resume Register and Suspend/Resume Interrupt Enable Register.
