1 _{The maximum vector number (479) is used to identify the location of the last available interrupt vector in memory for this device.}
Because blocks of memory throughout the total memory map are used for other purposes, the maximum vector number does
not indicate the total number of available interrupt sources for this device.
2 _{Interrupt requests from the same module location are ORed together.}
NOTE
The peripheral or software configurable interrupt request asserts when the
PRIn value in the interrupt priority select register (INTC_PSRn) is greater
than the PRIn value in interrupt current priority register (INTC_CPR).
If an asserted peripheral or software configurable interrupt request negates
before the processor acknowledges its request, the interrupt request can
reassert and remain asserted. If this occurs, the processor uses the
INTC_PSRn value to locate the IRQ vector, and updates the PRIn value in
the INTC_CPR with the PRIn value in INTC_PSRn.
