Interrupt Handling
The AT43USB355 provides 20 different interrupt sources with 11 separate reset vectors, each
with a separate program vector in the program memory space. Eleven of the interrupt sources
share 2 interrupt reset vectors. These 11 are the USB related interrupts. All interrupts are
assigned individual enable bits which must be set (one) together with the I-bit in the status reg-
ister in order to enable the interrupt.
The lowest addresses in the program memory space are automatically defined as the Reset
and Interrupt vectors. The complete list of vectors is shown in Table 6. The list also determines
the priority levels of the different interrupts. The lower the address, the higher is the priority
level. RESET has the highest priority, and next is INT0 – the USB Suspend and Resume Inter-
rupt, etc.
