In AVR microcontroller, the machine cycle is of 1 clock period of crystal frequency.Group of answer choicesTrueFalse

Answer

The statement is True.

Explanation

In AVR microcontrollers, the machine cycle is typically defined as the duration of one clock period, which corresponds to the frequency of the crystal or oscillator connected to the microcontroller. The AVR architecture is designed such that its instruction execution is synchronized with the clock signal generated by the crystal oscillator.

For example, if the microcontroller operates with a crystal frequency of 16 MHz, the duration of one machine cycle (or clock period) would be:

$\text{Clock period} = \frac{1}{\text{Frequency}} = \frac{1}{16 \times 10^6} \approx 62.5 \text{ nanoseconds}$

Each instruction takes a certain number of machine cycles to execute, and some instructions may take one machine cycle while others take multiple. Understanding this relationship is crucial for programming and optimizing performance in AVR microcontrollers. In summary, the machine cycle duration is indeed equivalent to one clock period of the crystal frequency, confirming the statement as true.
