-====== Timer Output ======
-\\ {{timer_output.svg}} \\ \\
-===== Programming Example =====
-The code snippet bellow shows how to configure and use a GPIO pin as input.
-<code c>
-#include "reg_stm32f4xx.h"
-RCC->AHB1ENR |= (0x1 << 0u);          /* Enable GPIOA clock */
-RCC->APB1ENR |= (0x1 << 0u);          /* Enable TIM2 clock */
-/* configure output */
-GPIOA->MODER |= (0x2 << 0u);          /* Set pin 0 to AF */
-GPIOA->AFR[0] |= (0x1 << 0u);         /* Set pin 0 to AF1 (TIM2) */
-/* configure basic timer */
-TIM2->PSC = 84000u - 1u;              /* Counting with f = 84MHz / 84000 = 1MHz */
-TIM2->ARR = 512u;                     /* Count to 512 */
-/* configure timer output */
-TIM2->CCMR1 |= (0x6 << 4u);           /* Enable PWM mode 1 on channel 1 */
-TIM2->CCER |= (0x1 << 0u);            /* Enable output on channel 1 */
-TIM2->CR1 |= (0x1 << 0u);             /* Start timer */
