Welcome in the forum.
Can you please post your complete project so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
You can OR the 4 signals together, and use the result as trigger for the interrupt.
No need for ORing, the status register is able to create an interrupt. As the datasheet says you will need to call StatusReg_WriteMask() and StatusReg_InterruptEnable() to setup the component.
But with the OR you don't get as many interrupts (only when the actual result changes, but not necessarily for each pin change)
Thanks for the comments.
I tried this method but if i have 4 status signals and in the initial case of configuring the int mask for all of them.Once i have one signal active at high, the interrupt its triggered.
Afterwards, in the ISR function, i must configure for each status bit, the corresponding interrupt mask and then, wait for another interrupt trigger in order to know which of the status bits was really changed.
