| //! \brief Configure AUX timer. |
| //! |
| //! This call configures the AUX timer selected by the \c ui32Timer. |
| //! The timer module is disabled before being configured and is left in the |
| //! disabled state. |
| //! |
| //! The configuration is specified in \c ui32Config as one of the following |
| //! values: |
| //! - \ref AUX_TIMER_CFG_ONE_SHOT : One-shot timer. |
| //! - \ref AUX_TIMER_CFG_PERIODIC : Periodic timer. |
| //! - \ref AUX_TIMER_CFG_ONE_SHOT_EDGE_COUNT : One-shot edge counter. |
| //! - \ref AUX_TIMER_CFG_PERIODIC_EDGE_COUNT : Periodic edge counter. |
| //! |
| //! When configured as timer, the counter is incremented based on the AUX clock |
| //! after the prescaler. The prescale division ratio is set |
| //! using \ref AUXTimerPrescaleSet(). |
| //! |
| //! When configured as an edge counter the counter is incremented only on edges |
| //! of the selected event. |
| //! The polarity of the event is selected by: |
| //! - \ref AUX_TIMER_CFG_RISING_EDGE : rising edge trigger |
| //! - \ref AUX_TIMER_CFG_FALLING_EDGE : falling edge trigger |
| //! |
| //! The event source is selected as one of the following defines: |
| //! - \ref AUX_TIMER_CFG_TICK_SRC_RTC_EVENT |
| //! - \ref AUX_TIMER_CFG_TICK_SRC_CMP_A |
| //! - \ref AUX_TIMER_CFG_TICK_SRC_CMP_B |

| //! - \ref AUX_TIMER_CFG_TICK_SRC_MCU_EVENT |
| //! - \ref AUX_TIMER_CFG_TICK_SRC_ADC_IRQ |
| //! |
| //! The mode, event polarity and event source are configured by setting the |
| //! \c ui32Config parameter as the bitwise OR of the various settings. |
| //! I.e. (\ref AUX_TIMER_CFG_ONE_SHOT_EDGE_COUNT | \ref AUX_TIMER_CFG_RISING_EDGE | |
| //! \ref AUX_TIMER_CFG_TICK_SRC_RTC_EVENT). |
| //! |
| //! \note When used as an edge counter the prescaler should be set to |
| //! \ref AUX_TIMER_PRESCALE_DIV_1. |
| //! |
| //! \note A timer can not trigger itself thus timer 0 can \b not use |
| //! \ref AUX_TIMER_CFG_TICK_SRC_TIMER0_EVENT and timer 1 can \b not use |
