Reset and Interrupt Handling
The AT43USB325 provides 12 different interrupt sources with 4 separate reset vectors, each
with a separate program vector in the program memory space. Nine of the interrupt sources
share 2 interrupt reset vectors. These nine 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 regis-
ter 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 4-1
. 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 Interrupt, etc.
