*
* This function validates the data integrity of the
* \ref cy_stc_capsense_widget_context_t data structure of the specified widget
* by calculating the CRC and comparing it with the stored CRC value of the
* specified widget.
*
* Initially, after the device power up, the Cy_CapSense_Enable() function
* calculates CRC for each widget and stores them in the .ptrWdgtCrc[] array
* of the \ref cy_stc_capsense_bist_context_t structure. The test execution
* compares this stored CRC value with the newly calculated and if the stored
* and calculated CRC values differ:
* 1. The calculated CRC is stored to the .wdgtCrcCalc field
* of the \ref cy_stc_capsense_bist_context_t data structure.
* 2. The widget ID is stored to the .crcWdgtId field.
* 3. The CY_CAPSENSE_BIST_CRC_WDGT_MASK bit is set in the .testResultMask field.
*
* The function never clears the CY_CAPSENSE_BIST_CRC_WDGT_MASK bit.
* If the CY_CAPSENSE_BIST_CRC_WDGT_MASK bit is set, the wdgtCrcCalc
* and .crcWdgtId fields are not updated.
*
* It is recommended to use the Cy_CapSense_SetParam() function to change
* the value of the \ref cy_stc_capsense_widget_context_t data structure elements
* as the CRC is updated by Cy_CapSense_SetParam() function.
*
* You can initiate this test by the Cy_CapSense_RunSelfTest() function with
* the CY_CAPSENSE_BIST_CRC_WDGT_MASK mask as an input.
*
* The function clears the CY_CAPSENSE_WD_WORKING_MASK bit of the .status
* field in \ref cy_stc_capsense_widget_context_t structure if the calculated
* CRC value differs to the stored CRC value.
* Those non-working widgets are skipped by the high-level scanning and
* processing functions. Restoring a widget to its working state should
* be done by the application level.
