/*******************************************************************************
* Function Name: Cy_CapSense_Init
****************************************************************************//**
*
* Captures HW blocks (one or more) for CAPSENSE™ operations and configures them
* to the default state. Call this function with the application program
* prior to calling any other function of the middleware.
*
* The following tasks are executed:
* 1. Capturing not used HW blocks. If any
* of HW blocks are
* already in use, then the function returns the fail status, and
* the application program should perform corresponding actions. For example, releasing
* the HW block captured by another middleware.
* 2. If the HW block has been captured successfully, this function configures it
* to the default state.
*
* After the middleware is configured using the Cy_CapSense_Init() function,
* the application program configures and enables the HW block interrupt(s),
* and then call of the Cy_CapSense_Enable() function to complete the
* middleware initialization process.
* See the function usage example below for more details.
*
* When the middleware operation is stopped by the Cy_CapSense_DeInit()
* function, subsequent call of the Cy_CapSense_Init() function repeats
* initialization process and it is not needed to call the Cy_CapSense_Enable()
* function second time. However, to implement time-multiplexed mode
* (sharing the HW block(s) between multiple middleware)
* the Cy_CapSense_Save() and Cy_CapSense_Restore() functions should be used
* instead of the Cy_CapSense_DeInit() and Cy_CapSense_Init() functions for
* further compatibility.
*
* \param context
* The pointer to the CAPSENSE™ context structure \ref cy_stc_capsense_context_t
* generated by the CAPSENSE™ Configurator tool. The structure contains both, CAPSENSE™
* configuration and internal data and it is used during whole CAPSENSE™ operation.
*
* \return
* Returns the status of the initialization process. If CY_CAPSENSE_STATUS_SUCCESS is not
* received, some of the initialization fails, the middleware may not operate
* as expected, and repeating of initialization is required.
*
* \funcusage
*
* \snippet capsense/snippet/main.c snippet_Cy_CapSense_Initialization
* The 'cy_capsense_context' variable that is used as the parameter of the
* Cy_CapSense_Init() and Cy_CapSense_Enable() functions is declared in the
* cycfg_capsense.h file.
*
* The CapSense_ISR_cfg variable should be declared by the application
* program according to the examples below:<br>
* For PSOC™ 4 CPU or for PSOC™ 6 CM0+ core:
* \snippet capsense/snippet/main.c snippet_m0p_capsense_interrupt_source_declaration
* \note MSCLP HW contains two interrupt sources.
* The CAPSENSE™ Middleware supports only the msclp_interrupt_<b>lp</b>_IRQn
* vector and therefore it should be used.
*
* For CM4 core:
* \snippet capsense/snippet/main.c snippet_m4_capsense_interrupt_source_declaration
*
* The CAPSENSE™ interrupt handler should be declared by the application program
* according to the example below:
* \snippet capsense/snippet/main.c snippet_Cy_CapSense_IntHandler
*
* The CapSense_HW is the pointer to the base register address of
* the CAPSENSE™ HW block. A macro for the pointer is in the cycfg_peripherals.h
* file defined as \<Personality_Name\>_HW. If no name is specified,
* the following default names are used:
* * csd_\<Block_Number\>_csd_\<Block_Number\>_HW - for forth-generation CAPSENSE™ HW.
* * msc_\<Block_Number\>_msc_\<Block_Number\>_HW - for fifth-generation CAPSENSE™ HW.
* * msclp_\<Block_Number\>_msclp_\<Block_Number\>_HW - for fifth-generation low power CAPSENSE™ HW.

* Function Name: Cy_CapSense_Enable
****************************************************************************//**
*
* Initializes the CAPSENSE™ firmware modules.
*
* Call the Cy_CapSense_Init() function and configure CAPSENSE™ HW block interrupts
* prior to calling this function.
* See the function usage example below for details on usage.
*
* The following are executed as part of the function:
* 1. Check CAPSENSE™ configuration integrity.
* 2. Pre-calculate of internal register values to speed up operation.
* 3. Configure the CAPSENSE™ HW block to perform capacitive sensing operation.
* 4. If the smart sensing algorithm is selected in the
* Basic tab, the auto-tuning functionality is executed to set the optimal
* values for the CAPSENSE™ HW block parameters of the widgets/sensors.
* 5. Calibrate the sensors and find the optimal values for DACs of each widget/sensor,
* if the auto-calibration is enabled in the CSD Settings, CSX Settings or ISX Settings tabs.
* 6. Perform scanning for all the sensors and initialize the baseline history.
* 7. If the firmware filters are enabled in the Advanced General tab, the
* filter histories are also initialized.
*
* Any subsequent call of this function repeats the initialization process.
* Therefore, it is possible to change the middleware configuration
* from the application program by writing registers to the data structure
* and calling this function again.
*
* The repeated call of this function is also done inside the
* Cy_CapSense_RunTuner() function when a restart command is received.
*
* The function calls the Cy_CapSense_ScanAllWidgets() function to proper
* baseline setup.
*
* \param context
* The pointer to the CAPSENSE™ context structure \ref cy_stc_capsense_context_t.
*
* \return
* Returns the status of the initialization process. If CY_CAPSENSE_STATUS_SUCCESS is not
* received, some of the initialization fails.
*
* \funcusage
*
* \snippet capsense/snippet/main.c snippet_Cy_CapSense_Initialization
* The 'cy_capsense_context' variable that is used as the parameter of the
* Cy_CapSense_Init() and Cy_CapSense_Enable() functions is declared in the
* cycfg_capsense.h file.
*
* The CapSense_ISR_cfg variable should be declared by the application
* program according to the examples below:<br>
* For CM0+ core:
* \snippet capsense/snippet/main.c snippet_m0p_capsense_interrupt_source_declaration
* \note MSCLP HW contains two interrupt sources.
* The CAPSENSE™ Middleware supports only the msclp_interrupt_<b>lp</b>_IRQn
* vector and therefore it should be used.
*
* For CM4 core:
* \snippet capsense/snippet/main.c snippet_m4_capsense_interrupt_source_declaration
*
* The CAPSENSE™ interrupt handler should be declared by the application program
* according to the example below:
* \snippet capsense/snippet/main.c snippet_Cy_CapSense_IntHandler
*
* The CapSense_HW is the pointer to the base register address of

/*******************************************************************************
* Function Name: Cy_CapSense_ProcessWidgetExt
****************************************************************************//**
*
* Performs customized data processing on the selected widget.
*
* This function performs customized data processing specified by the mode
* parameter on a widget. This function can be used with any of the
* available scan functions. This function should be called only after all
* the sensors in the specified widget are scanned. Calling this function
* multiple times with the same mode without new sensor scan causes
* unexpected behavior. This function ignores the widget statuses like
* disabled and/or non-working and performs processing in any case.
*
* The CY_CAPSENSE_PROCESS_CALC_NOISE and CY_CAPSENSE_PROCESS_THRESHOLDS masks
* for mode parameter are supported only when smart sensing algorithm is enabled.
*
* The execution order of processing tasks starts from LSB to MSB of the
* mode parameter. To implement a different order of execution, call this
* function multiple times with the required mode parameter.
*
* For more details, refer to function usage example below.
*
* \note
* For the fifth-generation CAPSENSE™ and fifth-generation low power
* CAPSENSE™ extra processing should be performed prior a call of
* this function:
* * A raw count pre-processing calling either the Cy_CapSense_PreProcessWidget()
* or Cy_CapSense_PreProcessSensor() functions.
* * A deconvolution for widgets with multi-phase Tx or Self calling the
* Cy_CapSense_ProcessWidgetMpDeconvolution() function
* (multi-phase Self is available only for the fifth-generation low power CAPSENSE™)
* In this case a full processing flow consists of the following:
* * Cy_CapSense_PreProcessWidget()
* * Cy_CapSense_ProcessWidgetMpDeconvolution()
* * Cy_CapSense_ProcessWidgetExt()
*
* For liquid level widget this function updates only widget status, other is skipped.
*
* \note
* For the fifth generation and fifth-generation low power CAPSENSE™
* if the specified widget has the enabled multi-frequency scan feature
* then the processing must follow the following order:
* * Sub-widget channel 2
* * Sub-widget channel 1
* * Main widget channel 0
* The CY_CAPSENSE_PROCESS_MFS_FILTER option is skipped for sub-widgets,
* however CY_CAPSENSE_PROCESS_STATUS option is available.
*
* \param widgetId
* Specifies the ID number of the widget. A macro for the widget ID can be found
* in the cycfg_capsense.h file defined as CY_CAPSENSE_<WIDGET_NAME>_WDGT_ID.
*
* \note For the fifth-generation low power CAPSENSE™ widgets
* of the \ref CY_CAPSENSE_WD_LOW_POWER_E type are not processed and
* \ref CY_CAPSENSE_STATUS_BAD_PARAM is returned
* if a widget of this type is passed.
*
* \param mode
* Specifies the type of widget processing to be executed for the
* specified widget:
* 1. Bits [31..7] - Reserved.
* 2. Bits [6..0] - CY_CAPSENSE_PROCESS_ALL - Execute all of the below tasks.
* 3. Bit [6] - CY_CAPSENSE_PROCESS_STATUS - Update the status
* (on/off, centroid position).
* 4. Bit [5] - CY_CAPSENSE_PROCESS_MFS_FILTER - Run the firmware filters
* for MFS on sensor rawcounts
* (applicable only for fifth-generation CAPSENSE™
* and fifth-generation low power CAPSENSE™).
* 5. Bit [4] - CY_CAPSENSE_PROCESS_THRESHOLDS - Update the thresholds
* (only in full auto-tuning mode).
* 6. Bit [3] - CY_CAPSENSE_PROCESS_CALC_NOISE - Calculate the noise
* (only in full auto-tuning mode).
* 7. Bit [2] - CY_CAPSENSE_PROCESS_DIFFCOUNTS - Update the difference
* counts of each sensor.
* 8. Bit [1] - CY_CAPSENSE_PROCESS_BASELINE - Update the baselines
* for all sensor.
* 9. Bit [0] - CY_CAPSENSE_PROCESS_FILTER - Run the firmware filters
* on sensor rawcounts.
*
* \param context
* The pointer to the CAPSENSE™ context structure \ref cy_stc_capsense_context_t.
*
* \return
* Returns the status of the widget processing operation:
* - CY_CAPSENSE_STATUS_SUCCESS - The processing is successfully performed.
* - CY_CAPSENSE_STATUS_BAD_PARAM - The input parameter is invalid.
* - CY_CAPSENSE_STATUS_BAD_DATA - The processing failed.
