*
* @brief Capture Compare Unit 8 (CCU8) low level driver for XMC family of microcontrollers<br>
*
* The CCU8 peripheral functions play a major role in applications that need complex Pulse Width Modulation (PWM) signal
* generation, with complementary high side and low side switches, multi phase control. These functions in conjunction
* with a very flexible and programmable signal conditioning scheme, make the CCU8 the must have peripheral for state
* of the art motor control, multi phase and multi level power electronics systems.\n
* Each CCU8 module is comprised of four identical 16 bit Capture/Compare Timer slices, CC8y (where y = [0..4]). Each
* timer slice can work in compare mode or in capture mode.
*
* APIs provided in this file cover the following functional blocks of CCU8:
* -- Timer configuration, Capture configuration, Function/Event configuration, Interrupt configuration
* \par Note:
* 1. SLICE (APIs prefixed with e.g. XMC_CCU8_SLICE_)
* 2. Module (APIs are not having any prefix e.g. XMC_CCU8_)
*
* \par Timer(Compare mode) configuration:
* This section of the LLD provides the configuration structure XMC_CCU8_SLICE_COMPARE_CONFIG_t,
* XMC_CCU8_SLICE_DEAD_TIME_CONFIG_t and the initialization functions XMC_CCU8_SLICE_CompareInit(), XMC_CCU8_SLICE_DeadTimeInit().
*
* It can be used to:
* -# Start and Stop the timer. (XMC_CCU8_SLICE_StartTimer(), XMC_CCU8_SLICE_StopTimer())
* -# Update the period, compare, Dither, Prescaler and Passive values. (XMC_CCU8_SLICE_SetTimerPeriodMatch(),
* XMC_CCU8_SLICE_SetTimerCompareMatch(), XMC_CCU8_SLICE_SetPrescaler(), XMC_CCU8_SLICE_SetDitherCompareValue(),
* XMC_CCU8_SLICE_SetPassiveLevel())
* -# Configure the dead time.(XMC_CCU8_SLICE_SetDeadTimeValue(), XMC_CCU8_SLICE_SetDeadTimePrescaler())
* -# Enable the slices to support multichannel mode. (XMC_CCU8_SLICE_EnableMultiChannelMode())
*
* \par Capture configuration:
* This section of the LLD provides the configuration structure XMC_CCU8_SLICE_CAPTURE_CONFIG_t and the initialization
* function XMC_CCU8_SLICE_CaptureInit().
*
* It can be used to:
* -# Configure the capture functionality. (XMC_CCU8_SLICE_Capture0Config(), XMC_CCU8_SLICE_Capture1Config())
* -# Read the captured values along with the status, which indicate the value is latest or not.
* (XMC_CCU8_SLICE_GetCaptureRegisterValue())
*
* \par Function/Event configuration:
* This section of the LLD provides the configuration structure XMC_CCU8_SLICE_EVENT_CONFIG_t.
*
* It can be used to:
* -# Enable and Disable the events. (XMC_CCU8_SLICE_EnableEvent(), XMC_CCU8_SLICE_DisableEvent())
* -# Configure to start and stop the timer on external events.(XMC_CCU8_SLICE_StartConfig(), XMC_CCU8_SLICE_StopConfig())
* -# Modulation, external load and Gating of the timer output.(XMC_CCU8_SLICE_ModulationConfig(),
* XMC_CCU8_SLICE_LoadConfig(), XMC_CCU8_SLICE_GateConfig())
* -# Control the count direction of the timer based on the external event. (XMC_CCU8_SLICE_DirectionConfig())
* -# Count the external events.(XMC_CCU8_SLICE_CountConfig())
* -# External Trap. Which can be used as protective feature.(XMC_CCU8_SLICE_EnableTrap(), XMC_CCU8_SLICE_DisableTrap(),
* XMC_CCU8_SLICE_TrapConfig())
*
* \par Interrupt configuration:
* This section of the LLD provides the function to configure the interrupt node to each event (XMC_CCU8_SLICE_SetInterruptNode())
