Table 8 Interrupt vector addresses and priority
Notes 1 : Vector addresses contain interrupt jump destination addresses.
2 : Reset function in the same way as an interrupt with the highest priority.
3 : In the mask option type P, timer 4 interrupt whose count source is CNTR1 input cannot be used.
4 : In the mask option type P, INT3 interrupt cannot be used.
