1．
答：定时值为10ms时，定时器T0工作在方式1时， 定时器T0对应的初值是1388H；（2分） TMOD的值是B； （1分） TH0=13H，TL0=88H。（3分） 2．
答：CPU在每个机器周期的S5P2期间顺序采样每个中断源，在下一个机器周期S6区间按优先级顺序查询中断标志，如查询到某个中断定标志为1，将在接下来的机器周期S1期间按优先级进行中断处理，中断系统通过硬件自动将相应的中断矢量地址装入PC，以便进入相应的中断服务程序。（3分）
一旦响应中断，CPU首先置位相应的中断“优先级触发器”，然后由硬件执行一条长调用指令，把当前的PC值压入堆栈，以保护断点，再将相应的中断服务的入口地址送入
