Solution

Claro, aquí tienes una explicación paso a paso:

  1. Registros del temporizador:

    • TCNTn (Timer/Counter Register): Este registro contiene el valor actual del contador del temporizador. Se incrementa o decrementa en cada ciclo de reloj, dependiendo de la configuración del temporizador.
    • TCCRn (Timer/Counter Control Register): Este registro se utiliza para configurar el modo de operación del temporizador, la fuente del reloj y el prescaler. Es esencial para definir cómo funcionará el temporizador.
    • OCRn (Output Compare Register): Este registro se utiliza para generar una señal de salida cuando el valor del contador (TCNTn) coincide con el valor almacenado en OCRn. Es útil en modos como CTC y PWM.
