FILE: interrupt_ex2_int_rtint_nesting.c
This example showcases nesting of INTs and RTINTs in groups using software interrupts and increments every time the software asserts an interrupt. The watch variables and print statements can be used to determine entry and exit points of ISR.
The interrupt priorities / group mask are configured as follows :
Order of Interrupt Triggers: INT1 -> INT2 -> INT3 -> RTINT1 -> RTINT2 -> RTINT3
Order of Interrupt Execution: INT1 -> INT3 -> RTINT1 -> RTINT3 -> RTINT1 -> RTINT2 -> INT3 -> INT1 -> INT2
Sysconfig inserts the required attributes to the ISR functions to inform the compiler that the function is an interrupt / realtime interrupt.
