- * @defgroup PWM PWM Driver
- * @brief   Generic PWM Driver.
- * @details This module implements a generic PWM (Pulse Width Modulation)
- *          driver.
- * @pre     In order to use the PWM driver the @p HAL_USE_PWM option
- *          must be enabled in @p halconf.h.
- *
- * @section pwm_1 Driver State Machine
- * The driver implements a state machine internally, not all the driver
- * functionalities can be used in any moment, any transition not explicitly
- * shown in the following diagram has to be considered an error and shall
- * be captured by an assertion (if enabled).
- * @dot
-  digraph example {
-    rankdir="LR";
-    node [shape=circle, fontname=Helvetica, fontsize=8, fixedsize="true", width="0.9", height="0.9"];
-    edge [fontname=Helvetica, fontsize=8];
-    uninit [label="PWM_UNINIT", style="bold"];
-    stop  [label="PWM_STOP\nLow Power"];
-    ready [label="PWM_READY\nClock Enabled"];
-    uninit -> stop [label="pwmInit()"];
-    stop -> stop [label="pwmStop()"];
-    stop -> ready [label="pwmStart()"];
-    ready -> stop [label="pwmStop()"];
-    ready -> ready [label="pwmEnableChannel()\npwmDisableChannel()"];
-  }

- *
- * @section pwm_2 PWM Operations.
- * This driver abstracts a generic PWM timer composed of:
- * - A clock prescaler.
- * - A main up counter.
- * - A comparator register that resets the main counter to zero when the limit
- *   is reached. An optional callback can be generated when this happens.
- * - An array of @p PWM_CHANNELS PWM channels, each channel has an output,
- *   a comparator and is able to invoke an optional callback when a comparator
- *   match with the main counter happens.
- * .
- * A PWM channel output can be in two different states:
- * - <b>IDLE</b>, when the channel is disabled or after a match occurred.
- * - <b>ACTIVE</b>, when the channel is enabled and a match didn't occur yet
- *   in the current PWM cycle.
- * .
- * Note that the two states can be associated to both logical zero or one in
- * the @p PWMChannelConfig structure.
