Mode 4 of Intel 8253 Timer - Square Wave Generation
Mode 4 of the Intel 8253 timer is also known as the square wave generation mode. In this mode, the timer continuously counts up or down based on the selected operating mode, and generates a square wave output signal with a 50% duty cycle.
Mode 4 is commonly used for generating square wave signals for various applications such as generating clock signals, controlling motors, and generating audio tones.
Key Points about Mode 4:
- In Mode 4, the timer counts up or down based on the selected operating mode.
- The output signal generated in Mode 4 has a 50% duty cycle, which means the signal is high for half of the total period and low for the other half.
- The square wave signal generated in Mode 4 can be used for various applications such as generating clock signals and controlling motors.
- Mode 4 is ideal for applications where a square wave signal with a 50% duty cycle is required.
In conclusion, Mode 4 of the Intel 8253 timer is specifically designed for generating square wave signals with a 50% duty cycle. This mode is commonly used in various applications that require a square wave signal for proper operation.
