Mode 3 in the Intel Timer 8253
Mode 3 in the Intel Timer 8253 is the Rate Generator.
Explanation:
- Rate Generator: In mode 3, the timer operates as a rate generator. It continuously generates pulses at a programmable frequency. The frequency is determined by the value loaded into the timer register.
- Usage: This mode is often used in scenarios where a consistent and regular output signal is required, such as for generating clock signals or for timing intervals.
- Programming: To set the timer 8253 in mode 3, specific control word values are written to the control register. These values specify the mode of operation and other parameters like the frequency at which the pulses should be generated.
- Characteristics: The rate generator mode allows for precise control over the frequency of the generated pulses. By adjusting the value in the timer register, the output frequency can be changed dynamically.
- Advantages: This mode offers flexibility in generating output signals with different frequencies, making it suitable for various applications that require a stable and adjustable timing source.
In conclusion, mode 3 in the Intel Timer 8253 is the Rate Generator, which continuously generates pulses at a programmable frequency. This mode is useful for applications that require a consistent and adjustable output signal.
