What are the advantages disadvantages and characteristics of C51 microcontroller interrupts respectively

Traditional microcontroller interrupts five. Including two external interrupts (int0,int1), three timing interrupts (t2,t1,t0), and a serial port interrupt (uart).

Features:Simple and intuitive, easy to control Advantages

Advantages:

Fast response, level- and clock-triggered interrupts, counting interrupts, timing interrupts, interrupts from serial port data, sleep interrupts wake-up mode interrupts.

Disadvantages:

Only a single-task mechanism can be used, the program can only be executed in sequential order, the lack of flexibility, you can only use the interrupt function in real time to deal with a number of shorter tasks, the use of more complex applications is extremely inconvenient.
