| ****************************************************************************//** | |
| * | |
| * Initiates the non-blocking scan of all Active slots and then exits. Scanning | |
| * is initiated only if no scan is in progress. To initiate all Low Power slot | |
| * scan use the Cy_CapSense_ScanAllLpSlots() function. | |
| * The status of the current scan should be checked using the Cy_CapSense_IsBusy() | |
| * function and the application program waits until all scans are finished prior | |
| * to starting a next scan by using this function. | |
| * | |
| * \par | |
| * * For fifth-generation low power CAPSENSE™ | |
| * This function loads slots configurations into the internal buffer of the | |
| * CAPSENSE™ hardware block and triggers scanning. | |
| * If the scan frame doesn`t fit into the internal buffer it will be processed as | |
| * the sequence of sub-frames. Next sub-frame will be loaded by the interrupt | |
| * service routine(part of middleware) once scan of previous sub-frame is complete. | |
| * The scanning process duration consists of a some | |
| * pre-configured interval and a frame scan duration. The first slot scan starts | |
| * after the pre-configured interval. The default duration of the interval is | |
| * 1 ILO cycle. The interval duration can be changed | |
| * by the Cy_CapSense_ConfigureMsclpTimer() function. | |
| * If the "Enable external frame start" option is disabled in the CAPSENSE™ | |
| * Configurator, the scanning process will be triggered immediately. | |
| * If the "Enable external frame start" option is enabled in the CAPSENSE™ | |
| * Configurator, the scanning process will be triggered by the first external | |
| * synchronization signal after call of the function. | |
| * The number of slots in frame in this case should not exceed the maximum | |
| * possible slot number to fit into the internal buffer of the CAPSENSE™ | |
| * hardware block. | |
| * The External synchronization signal parameters should meet the following | |
| * constraints: | |
| * * - the interval between the return of the function and the rising edge | |
| * of an external synchronization signal must not be less than 2 ILO cycles; | |
| * * - the pulse duration of an external synchronization signal | |
| * (i.e. signal is in High level) must not be less than 2 ILO cycles and more | |
| * than the full scanning process duration. The full scanning process | |
| * duration is the time between the rising edge of the external | |
| * synchronization pulse and clearing of BUSY flag. The Cy_CapSense_IsBusy() | |
| * function can be used to check BUSY flag; | |
| * * - the interval between sub-sequent pulses should not be less than full | |
| * scanning process duration. | |
| * Disregarding the "Enable external frame start" option, the transition into | |
| * system DEEP SLEEP mode is allowed after the scan process is started | |
| * by the function. | |
| * To decrease the start scan time when it is intended to scan the same frame, | |
| * i.e. startSlotId and numberSlots parameters are the same, then the scan | |
| * is performed without the MSC HW block reconfiguration. | |
| * The number of slots in frame in this case should not exceed the maximum | |

| * hardware block. | |
| * | |
| * \par | |
| * * For fifth-generation CAPSENSE™ this function initiates a scan for | |
| * the first slot for all channels and then exits. Scans for the remaining slots | |
| * in the Interrupt-driven scan mode are initiated in the interrupt service | |
| * routine (part of middleware) triggered at the end | |
| * of each scan completion for each channel. If the syncMode field in the | |
| * cy_stc_capsense_common_config_t structure is set to CY_CAPSENSE_SYNC_MODE_OFF, | |
| * then the next slot scan for the channel with the fired interrupt, | |
| * will start regardless of the another channel readiness for the next scan. | |
| * If the syncMode field is set to CY_CAPSENSE_SYNC_INTERNAL (for single-chip projects) | |
| * or to CY_CAPSENSE_SYNC_EXTERNAL (for multi-chip projects), | |
| * then the next slot scan for the channel with the fired interrupt, | |
| * will start in lockstep with another channels after they all are ready | |
| * for the next scan (the next scan configuration is loaded into the channel MSC HW block). | |
| * Scans for the remaining slots in CS-DMA scan mode are initiated | |
| * by DMAC triggered at the end | |
| * of each scan completion for each channel. The channel scan synchronization is | |
| * performed as in Interrupt-driven scan mode. After all slots are scanned, | |
| * the FRAME interrupt is fired and the interrupt service routine (part of middleware) | |

| * The function changes the configuration of an electrode without storing | |
| * the previous state. A user is responsible to keep the previous state to | |
| * revert to the default settings if needed. Also, the default settings | |
| * can be configured again by calling Cy_CapSense_Enable() function that | |
| * leads to repeating CAPSENSE™ Data Structure initialization, | |
| * DAC auto-calibration, and baseline initialization. | |
| * | |
| * Using the function is recommended only for advanced users for specific use cases. | |
| * For instance, to change the CAPSENSE™ default electrode configuration, | |
| * the function could be called by using a CAPSENSE™ Data Structure | |
| * Initialization callback ptrEODsInitCallback. For details of how to register | |
| * the callback see the \ref group_capsense_callbacks section. That avoids repeating of | |
| * DAC auto-calibration and baseline initialization since the callback is called after | |
| * CAPSENSE™ Data Structure initialization but before the first initialization | |
| * scan. | |
| * | |
| * You can also use this function to change the shield electrode state - call the function | |
| * and pass the pointer to the shield electrode configuration as an input parameter. | |
| * | |
| * \note | |
| * This function is available for the fifth-generation (only | |
| * for CY_CAPSENSE_CTRLMUX_SENSOR_CONNECTION_METHOD) and fifth-generation low power | |

| * Sets a desired state for all inactive CAPSENSE™-related electrodes | |

| * | |
| * Use the function to set/change the desired state | |
| * of all CAPSENSE™-related | |
| * electrodes which are not scanned during regular scans or BIST capacitance | |
| * measurements. There are separate states for the CSD | |
| * sensing method group, the CSX sensing method group, the ISX sensing method | |
| * group, the BIST CSD sensor | |
| * (electrode) capacitance measurement, the BIST CSX sensor | |
| * (electrode) capacitance measurement, and the BIST shield electrode | |
| * capacitance measurement. For instance, it can be configured the GND state | |
| * for all inactive sensors for CSX scanning and the High-Z state for CSD | |
| * scanning and the Shield state for BIST CSD sensor (electrode) capacitance | |
| * measurement. | |
| * The function updates some corresponding parameters in the CAPSENSE™ Data | |
| * Structure to provide the desired state and not changes pin state immediately. | |
| * The desired state will be applied to all inactive electrodes | |
