+
+上表中的地址是按16bit算的
+
+编写对应的中断程序，以`TIMER1_OVF`举例，按如下格式
+
+```
+extern "C" void __vector_16() __attribute__ ((signal,used, externally_visible));
+void __vector_16()
+{
+	// ...
+}
+```
+
+### 中断向量表所在位置
+|BOOTRST| IVSEL| Reset Address| Interrupt Vectors Start Address|
+|---|---|---|:--|
+|1| 0| 0x000| 0x002|
+|1| 1| 0x000| Boot Reset Address + 0x0002|
+|0| 0| Boot Reset Address| 0x002|
+|0| 1| Boot Reset Address| Boot Reset Address + 0x0002|
+
+* BOOTRST是fuse.high_byte.BOOTRST比特们，1表示unprogramed，reset时从地址0开始，0表示programed，reset时从地址`Boot Reset Address`开始
+* 地址`Boot Reset Address`与BOOTSZ即fuse.hih_byte[2:1]相关
+* IVSEL是MCUCR寄存器的第1个bit
+
+### 外部中断
+* 如果启用中断，就算将INT、PCINT引脚配置成`OUTPUT`也会触发中断
+### PCINT和INT引脚的差别
+* INT限制在了两个端口上面，而PCINT则是所有接口都具备。
+* INT具有上沿，下沿，低电平，高电平触发这几种模式，而PCINT只有测量电平的变化这一个模式。
+* INT可以了解具体是哪个口触发的，而PCINT不行。
+* PCINT不会直接跳转入指定的程序，用户需要读取寄存器来做判断是哪个PCINT端口产生了变化。
+* INT0和INT1各自可配置一个中断程序入口，而所有的PCINT都只会触发跳转进入一条指定的程序。
