 This update enhances the user experience by making the code more intuitive and aligned with the familiar Arduino programming style.
 
-***When using the Analog Output channels, please consider following detail: The High-Resolution Timer (HRTIM) function on PG7 allows for high-frequency PWM signals with precise control over short periods. However, it is limited to a maximum period of __approximately 1.3 ms__. This constraint makes __Analog Out Channel 2__ optimal for high-frequency PWM applications but unsuitable for periods exceeding 1.3 ms. For longer periods, alternative __Analog Out channels (AO0, AO1, AO3)__ with standard timers are recommended. Please refer to the [Portenta Machine Control User Manual: Analog Outputs secion](https://docs.arduino.cc/tutorials/portenta-machine-control/user-manual/#analog-outputs) for more details.***
