ask question about mmc2107 interrupt

[Áηå]

hello,
    I am a green hand in the study of mmc2107,and I am so confused about this kind
of cpu's interrupt handling. So, I hope you can give me some advice on how to
arrange a routine to handle one interrupt,especially the external interrupts.
And if you have some examples about handling interrup with c and asm languages,
could you send to me to study?
    Thank you!
