IP1(SFR 0xB9) (Table 36). If requests of the same priority level are received simultaneously, an internal
polling sequence as shown in Table 37 determines which request is serviced first.
Changing interrupt priorities while interrupts are enabled can easily cause software defects. It is best
to set the interrupt priority registers only once during initialization before interrupts are enabled.
