Multi-Function Interrupts
If an interrupt requires immediate servicing while the program is already in another interrupt service
routine, the EMI bit should be set after entering the routine, to allow interrupt nesting. If the stack is
full, the interrupt request will not be acknowledged, even if the related interrupt is enabled, until the
Stack Pointer is decremented. If immediate service is desired, the stack must be prevented from
becoming full. In case of simultaneous requests, the accompanying diagram shows the priority that is
applied. All of the interrupt request flags when set will wake-up the device if it is in SLEEP or IDLE
Mode, however to prevent a wake-up from occurring the corresponding flag should be set before the
device is in SLEEP or IDLE Mode.
