Erik Malund said:
ONLY If two interrupts occur at the exact same time (same cycle), the interrupt with higher priority will execute first.
The above is (without the above emphasis), probably the most misread piece in "the bible" Erik You sure about that? Shouldn't you write: Only if two interrupts becomes possible at the same clock cycle? An interrupt may become possible for a number of reasons - the end of an interrupt handler, the enabling of an interrupt flag or some form of event matching an interrupt event. |
