Function Descriptions
– For selecting different priorities for different interrupts you must call the function more than
– This function is for Nested Interrupts only.
Caution:
– If you select an interrupt which is not present in the Peripheral then you will get an error mes-

them together by logically ORing.
sage during compilation.
iour has to be considered:
If that interrupt is still pending, and the new software priority is higher than the previous one,
the interrupt is re-entered. Otherwise the software priority stays unchanged until the next in-
terrupt request.
Returns the Interrupt software priority level of the current
Interrupt.
None
IT_LEVEL_0
Software Priority of the current interrupt is at Level0
IT_LEVEL_1
Software Priority of the current interrupt is at Level1
