 *
 * Change History
 * --------------
 *
 * 2015-02-20:
 *     - Initial <br>
 *
 * 2015-06-20:
 *     - Removed definition of GetDriverVersion API <br>
 *
 * 2015-07-01:
 *     - In XMC_CCU4_SLICE_StartConfig(), Options in XMC_ASSERT check for start mode is corrected. <br>
 *
 * 2015-07-24:
 *     - XMC_CCU4_SLICE_ConfigureStatusBitOverrideEvent() is updated to support XMC14 device. <br>
 *
 * 2015-08-17:
 *     - Start of prescaler XMC_CCU4_StartPrescaler() is invoked in XMC_CCU4_Init() API. <br>
 *     - Bug fix XMC_CCU4_SLICE_ConfigureEvent() during the level setting for XMC14 devices. <br>
 *     - XMC_CCU4_EnableShadowTransfer() definition is removed, since the API is made as inline. <br>
 *
 * 2015-10-07:
 *     - XMC_CCU4_SLICE_GetEvent() is made as inline.
 *     - DOC updates for the newly added APIs.
 *
 * 2017-02-25:
 *     - XMC_CCU4_lAssertReset(), XMC_CCU4_lDeassertReset(), XMC_CCU4_lGateClock() and XMC_CCU4_lUngateClock() fix compilation warnings.
 *
 * 2017-04-27:
 *     - XMC_CCU4_SLICE_SetPrescaler() changed div_val parameter to type XMC_CCU4_SLICE_PRESCALER_t
