I've browsed through this forum and your programming guide and still felt i'm gonna just tell you what i need.

i now have 3 external interrupts. 1 connect to IRQ0, 1 to P0I,and 1 to P12I

so i want the IRQ0 ISR to be able to run regardless of the status of other 2 interrupts and not to be disturbed while it's running.

the other 2 ISR i would like them to be interruptible by IRQ0 while they are preferred not to interfere with each other.

is this description clear?

how should i setup IMASKP register to achieve such a goal?
