(15) Interrupts: 19 sources, 10 vectors

1) Three priority (low, high and highest) multiple interrupts are supported. During interrupt handling,

an equal or lower priority interrupt request is postponed.

2) If interrupt requests to two or more vector addresses occur at once, the higher priority interrupt takes

precedence. In the case of equal priority levels, the vector with the lowest address takes

precedence.

No.
