AT91SAM7XC512/256/128
– Higher priority interrupts can be served during service of lower priority interrupt
Vectoring
– Optimizes interrupt service routine branch and execution
– One 32-bit vector register per interrupt source
– Interrupt vector register reads the corresponding current interrupt vector
Protect Mode
– Easy debugging by preventing automatic operations
Fast Forcing
– Permits redirecting any interrupt source on the fast interrupt
General Interrupt Mask
– Provides processor synchronization on events without triggering an interrupt
9.5
