If another enabled interrupt of the same type occurs before being acknowledged by the software ISR, it will
be lost because no counting or queuing is used. However, this condition is detected and stored in the top-level
INT_MISS
edged” in the same way as the
If another enabled interrupt occurs after being acknowledged but while interrupts remain disabled, the CPU
will be re-interrupted to service it when the software ISR returns and interrupts are re-enabled.
Applications only have write access to certain bits in the top-level
ters that pertain to application peripherals. They have full access to second-level
INT_periphCFG
from application interference.
Applications can also trigger a software interrupt by writing into the
responsible for processing and acknowledging this interrupt.
The EM250 also provides a global
