void _IRQ(_PMP_VECTOR, ipl3) PMP_Interrupt_ISR(void)
{
}
The following code example illustrates a PMP interrupt configuration.
When the PMP interrupt is generated, the CPU will branch to the vector
assigned to PMP interrupt.
// Configure PMP for desired mode of operation
...
// Configure the PMP interrupts
IPC7SET = 0x0014;
IPC7SET = 0x0003;
IFS1CLR
IEC1SET
PMCONSET = 0x8000;
The following code example demonstrates a simple interrupt
service routine for PMP interrupts. The user’s code at this
vector should perform any application specific operations and must
clear the PMP interrupt status flag before exiting.
... perform application specific operations in response to the interrupt

PMP MODULE INTERRUPT INITIALIZATION
PMP ISR
// Set priority level=5
// Set subpriority level=3
// Could have also done this in single
// operation by assigning IPC7SET = 0x0017
// Clear the PMP interrupt status flag
// Enable PMP interrupts
// Enable PMP module
// Be sure to clear the PMP interrupt status
// flag before exiting the service routine.
