<> 128:9bcdf88f62b0 56 * The CRYOTIMER is a 32 bit counter which operates on a low frequency
<> 128:9bcdf88f62b0 57 * oscillator, and is capable of running in all Energy Modes. It can provide
<> 128:9bcdf88f62b0 58 * periodic wakeup events and PRS signals which can be used to wake up
<> 128:9bcdf88f62b0 59 * peripherals from any energy mode. The CRYOTIMER provides a very wide range
<> 128:9bcdf88f62b0 60 * of periods for the interrupts facilitating flexible ultra-low energy
<> 128:9bcdf88f62b0 61 * operation. Because of its simplicity, the CRYOTIMER is a lower energy
<> 128:9bcdf88f62b0 62 * solution for periodically waking up the MCU compared to the RTCC.
<> 128:9bcdf88f62b0 63 *
<> 128:9bcdf88f62b0 64 * To configure the CRYOTIMER you call the @ref CRYOTIMER_Init function.
<> 128:9bcdf88f62b0 65 * This function will configure the CRYOTIMER peripheral according to the
<> 128:9bcdf88f62b0 66 * user configuration.

<> 128:9bcdf88f62b0 68 * @details
<> 128:9bcdf88f62b0 69 * When using the CRYOTIMER the user has to choose which oscillator to use
<> 128:9bcdf88f62b0 70 * as the CRYOTIMER clock. The CRYOTIMER supports 3 low frequency clock
<> 128:9bcdf88f62b0 71 * these are LFXO, LFRCO and ULFRCO. The oscillator that is chosen must be
<> 128:9bcdf88f62b0 72 * enabled and ready before calling this @ref CRYOTIMER_Init function.
<> 128:9bcdf88f62b0 73 * See @ref CMU_OscillatorEnable for details of how to enable and wait for an
<> 128:9bcdf88f62b0 74 * oscillator to become ready. Note that ULFRCO is always ready while LFRCO
<> 128:9bcdf88f62b0 75 * @ref cmuOsc_LFRCO and LFXO @ref cmuOsc_LFXO must be enabled by the user.

Kojto 113:f141b2784e32 77 * @details
Kojto 113:f141b2784e32 78 * Note that the only oscillator which is running in EM3 is ULFRCO. Keep this
Kojto 113:f141b2784e32 79 * in mind when choosing which oscillator to use for the CRYOTIMER.
Kojto 113:f141b2784e32 80 *
<> 128:9bcdf88f62b0 81 * Here is an example of how to use the CRYOTIMER to generate an interrupt
<> 128:9bcdf88f62b0 82 * at a configurable period.

Kojto 113:f141b2784e32 86 * @details
<> 128:9bcdf88f62b0 87 * To use the CRYOTIMER in EM4 the user has to enable EM4 wakeup in the
<> 128:9bcdf88f62b0 88 * CRYOTIMER. This can be done either in the @ref CRYOTIMER_Init_TypeDef
<> 128:9bcdf88f62b0 89 * structure when initializing the CRYOTIMER or at a later time by using
<> 128:9bcdf88f62b0 90 * @ref CRYOTIMER_EM4WakeupEnable.
<> 128:9bcdf88f62b0 91 *
<> 128:9bcdf88f62b0 92 * Note that when using the CRYOTIMER to wakeup from EM4 the application has
<> 128:9bcdf88f62b0 93 * the responsibility to clear the wakeup event. This is done by calling
<> 128:9bcdf88f62b0 94 * @ref CRYOTIMER_IntClear. If the user does not clear the wakeup event then
<> 128:9bcdf88f62b0 95 * the wakeup event will stay pending and will cause an immediate wakeup the
<> 128:9bcdf88f62b0 96 * next time the application attempts to enter EM4.
<> 128:9bcdf88f62b0 97 *
<> 128:9bcdf88f62b0 98 * Here is an example of how to use the CRYOTIMER to wakeup from EM4 after
<> 128:9bcdf88f62b0 99 * a configurable amount of time.
<> 128:9bcdf88f62b0 100 *

Kojto 113:f141b2784e32 105 * oscillator that is used must be be configured to be retained when going
Kojto 113:f141b2784e32 106 * into EM4. This can be configured by using functions in the @ref EMU module.
Kojto 113:f141b2784e32 107 * See @ref EMU_EM4Init and @ref EMU_EM4Init_TypeDef. If an oscillator is
Kojto 113:f141b2784e32 108 * retained in EM4 the user is also responsible for unlatching the retained
Kojto 113:f141b2784e32 109 * configuration on a wakeup from EM4.
