I've browsed through this forum and your programming guide and still felt confused...so 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?
