Why does the MCS-51 microcontroller need to interrupt the system expansion? How does the timer serve as an external interrupt source?
Why does the MCS-51 microcontroller need to use interrupt system expansion?
Answer: Although MCS-51 has provided two external interrupt request input terminals INT0 and INT1, when there is still a large demand for external interrupt request sources, interrupt system expansion is required.
When the timer is used as
