各位大神，新手首次调ADC，其中配置部分 两次差分通道选择（红色字体），请问这两个配置什么区别？求大神指教。多谢！
typedef struct CAdcChnConfig
{
    cadc_diff_chn_t diffChns; /*!< Select the differential channel pair. @internal gui name="Channel" */
    cadc_chn_sel_mode_t diffSelMode; /*!< Select which channel is indicated in a pair. @internal gui name="Differential mode" */
    cadc_gain_mode_t gainMode; /*!< Gain mode for each channel. @internal gui name="Gain" */
} cadc_chn_config_t;

typedef struct CAdcSlotConfig
{
    bool slotDisable; /*!< Keep the slot unavailable. @internal gui name="Slot" */
    bool syncPointEnable; /*!< Sample waits for an enabled SYNC input to occur. @internal gui name="Synchronization point" */
    bool syncIntEnable; /*!< Scan interrupt enable. @internal gui name="Scan interrupt" */

    /* Select the input channel for slot. */
    cadc_diff_chn_t diffChns;  /*!< Select the differential pair. @internal gui name="Channel pair" id="diffSlotChns" */
    cadc_chn_sel_mode_t  diffSel;   /*!< Positive or negative channel in differential pair. @internal gui name="Channel select" */

    /* Event detection mode. */
    cadc_zero_crossing_mode_t zeroCrossingMode; /*!< Select zero crossing detection mode. @internal gui name="Zero cross mode" */
    uint16_t lowLimitValue; /*!< Select low limit for hardware compare. @internal gui name="Low limit compare value" range="0..32760" */
    uint16_t highLimitValue;/*!< Select high limit for hardware compare. @internal gui name="High limit compare value" range="0..32760" */
    uint16_t offsetValue;   /*!< Select sign change limit for hardware compare. @internal gui name="Offset value" range="0..32760" */
} cadc_slot_config_t;

MKV46F256，KSDK1.3版本。

关于这个问题，可以到KV46手册中查看：
The slots are used to define which input or differential pair to measure at each step in a scan sequence. The
SDIS register defines which sample slots are enabled.
