| 摘 要： | 分别使用6MHz和12MHz晶振频率，测试MCS-51系统的外部中断响应频率。实验结果表明：由于中断服务时间和中断响应延迟的存在，MCS-51系统的外部中断响应频率是受到限制的；最高可测试的外部中断响应频率大约是65kHz。本实验为合理和有效应用MCS-51系统的中断控制资源提供了可靠的实验数据。

| Abstract: | Using 6 MHz or 12 MHz quartz oscillator respectively, to measure the external interrupts response frequency of mcs-51 system. The experiment results showed that due to exist the interrupt service time and interrupt response latency, the external interrupt response frequency of mcs-51 system is limited; the maximum measurable external interrupt response frequency is about 65 kHz. The measured results provide reliable experiment data for to apply suitably and efficiently the interrupt control resource within mcs-51 system. |
