NettetThere are two external interrupt pins on the ATmega168/328 called INT0 and INT1. both INT0 and INT1 are mapped to pins 2 and 3. In contrast, Pin Change interrupts can be activated on any of the pins. Arduino Uno Pinout - ICSP Header ICSP stands for In-Circuit Serial Programming. The name originated from In-System Programming … NettetIT0=0时,INT0为低电平触发方式。 IT0=1时,INT0为负跳变触发方式。 IE0:INT0中断请求标志位。 当有外部的中断请求时,该位置1(这由硬件来完成),在CPU响应中断后,由硬件将IE0清0。 IT1、IE1的用途和IT0、IE0相似。 内部请求源: TF0:定时/计数器T0溢出中断标记,当T0产生溢出时,TF0置位。 当CPU响应中断后,硬件将TF0复位 …
